1) It's generally not a good idea to mess with ownership. A well designed and built user application will always provide for user read and execute of the program file. A system application has to be owned by root, but may provide for a group to which a user may belong if there is some - such as printing. If you go into a konsole and enter the command "groups", it will shows you what groups you are a member of for system applications that you personally are allowed to interact with, like this:

Code:

john@john-Desktop:/tmp$ groups
john adm cdrom sudo dip plugdev lpadmin sambashare
john@john-Desktop:/tmp$

2) Generally speaking /home is where your data goes, with some users making use of the /mnt directory for extended file storage. And /media is usually where plug in devices like USB drives may find themselves mounted. Right now I have this structure (no USB drives plugged in at the moment):

Code:

john@john-Desktop:/$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            7.8G     0  7.8G   0% /dev
tmpfs           1.6G  1.6M  1.6G   1% /run
/dev/sda2        37G   11G   24G  31% /
tmpfs           7.8G   45M  7.8G   1% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           7.8G     0  7.8G   0% /sys/fs/cgroup
/dev/sda1       476M  6.1M  469M   2% /boot/efi
/dev/sda3        95G   27G   64G  30% /home
/dev/sdb1       293G   67G  212G  24% /home/multimedia
tmpfs           1.6G     0  1.6G   0% /run/user/119
tmpfs           1.6G   36K  1.6G   1% /run/user/1000

You can see that I choose to have a regular /home where a lot of my documents, and the configs for the apps I use go, and a /home/multimedia on a separate drive where my music, photos, videos, and the like go. The drives for both those directories are always mounted at boot time and are internal drives in the desktop PC. You can also see that the system also mounts a whole bunch of other small partitions - that are temporary.

3) which brings up the question of what is "FILES" in you layout. Do you have a separate partition that is used to mount a directory named FILES? Not saying its illegal or anything

, just unusual. Also, what do you anticipate storing in FILES?

4) It's usually not a good thing to install applications to /home, precisely because of ownership and permissions issues. An application installed to /home can, and most likely will completely screw permissions on the entire directory. So don't mix data and applications, even if you think you "own" the application because you install the application. The /opt directory is often used for applications that are installed outside the OS's normal packaging system. If you can find an application that uses the Kubuntu Debian packaging system, it will usually behave much better than some others. Snaps and flatpaks are outside the Debian method, also. And even if a particular application is several versions ahead of the Debian version, the Debian version is compiled against the kernel and libraries that are in the current Kubuntu version, so they will run more smoothly. There are exceptions, but you most definitely do not run down a rabbit hole of chasing kernels and libraries that work with some application and not so well with the rest of Kubuntu. There are people who actually build their own Linux from top to bottom. But they are rare birds.

5) Did you install or plugin some hardware, or some non standard app or library before that started to show? Or was that the immediate result after your re-install?

**TwoFistedJustice** · Feb 08, 2019, 10:03 PM

Thank you jglen940 for you help!

3) "files" are anything I want to keep for a long time: pictures, config files, word docs, etc. Maybe "hoard" (as in "My neighbor is a hoarder who has a hoard") is a better word for this drive than "files". So I have a logical Hoard-drive.

4) Ok I did a bad thing then and installed a couple of apps to Home. Chrome and postman I think. Do you think this may be what kicked me into emergency mode?

5) Nothing that should affect that. I did install MongoDB official version, then I had to uninstall it because it doesn't work, and re-install Ubuntu's native Mongo packages. - Is there a way to fix the ACPI drivers in emergency mode?

**jglen490** · Feb 09, 2019, 11:32 AM

Typically, the Thinkpad series of laptops are well supported by all Linux distros. The hardware is pretty common and therefore the needed libraries and other objects are a prt of the basic install. For your "files", which you define about the same way that I define what is in my /home/multimedia, can go under /home as I do or under /mnt as others do. I would not recommend using /media for that purpose - there MIGHT be a conflict with some transient mount such as a USB drive. You can put it in a separate partition on the hard drive or just keep it in a subdirectory under either /home or /mnt and just make sure you provide enough space in the associated partition.

Right now your ACPI issues seem to be warnings and not errors, so if there is something that needs to be installed or updated that can be done within the session. Installs can be done with the Synaptic GUI or apt in konsole. I'm not all that familiar with the specific issue you seem to have with

shpchp: Standard Hot Plug PCI Controller Driver version: 0.4

I used to have an older Thinkpad, but not now. While I do see that specific kernel module on my desktop PC, no problems or errors or warnings show in my logs. What I did to determine that is in konsole enter:

Code:

john@john-Desktop:/$ sudo find / -name shpchp*
[sudo] password for john: 
/lib/modules/4.15.0-44-generic/kernel/drivers/pci/hotplug/shpchp.ko
/lib/modules/4.15.0-45-generic/kernel/drivers/pci/hotplug/shpchp.ko
find: ‘/proc/2023/task/2023/net’: Invalid argument

/sys/module/shpchp/parameters/shpchp_poll_time
/sys/module/shpchp/parameters/shpchp_poll_mode
/sys/module/shpchp/parameters/shpchp_debug

Which shows that is is present.
And then:

Code:

Which shows no errors or warnings.

Your situation will probably be different, and may be due to installing or plugging in additional hardware not normally a part of your laptop.

**oshunluvr** · Feb 09, 2019, 12:42 PM

I'm just going to pile onto most of what jglen490 has already said:

Originally posted by TwoFistedJustice View Post

1) Ownership. Some files and non-native applications (Webstorm, Postman, Robomongo, etc) seemed to be owned by root, and others by User.
How do i make it so that User owns all the files that I create and all the non-native applications that I install ?
Am I even barking up the right tree?

Totally barking up the wrong tree. You are admittedly new to Linux so I suggest doing a little reading on file permissions and ownership since Windows does nothing of the sort. Not an uncommon thing for a new Linux user to question, but an unbelievably bad idea to mess with until you're are exactly sure you're doing the right thing. My advice: leave all that in the system areas totally alone until you're advised to do something different. The whole reason you have a home folder is because that's where stuff you (as a user) should be mucking around. Also worth knowing: generally any system wide settings you might need or want to change would be in the /etc/ folder. Be very cautious about going outside there. BTW, just because it is in your home folder doesn't mean it's harmless either. Many many users here end up damaging their home settings enough that they can't get back to the desktop.

One thing to consider - if you're going to experiment with things in your home, simply make a second user and log into that account to experiment. If your experiment works out, you can repeat the process as your regular user. If it doesn't, just delete the second user account and make a new one in it's place.

2) I keep all of my important files on a separate partition. In Windows I used a logical partition D:/ for this. I tried the same thing in Linux and found that some programs, (i.e. Webstorm) couldn't write to that drive. So now I've lost my settings file for Linux.
How do I make it so Webstorm and other applications can fully access my files drive?

This is probably a file system issue. Windows by default uses NTFS and can't read or write to Linux file systems - of which there are dozens. Most Linux file systems use "journaling" which makes them safer from corruptions. It is ill advised to use NTFS, EXFAT, or VFAT for any files you really want to protect, but NTFS is safe enough IF you have a backup - which you should anyway. The simplest solution here is to install the NTFS tools in Linux and format a partition in NTFS to share for both operating systems.

3) My partition set up looked something like this:
ROOT ~20G
HOME ~ 30G
SWAP ~ 8G
FILES - The rest of the drive space

What is an optimal partition scheme for Kubuntu given a 256G ssd?

"Optimal" is too subjective to reply to without knowing how you use your system. The only comment I have at this point is if the majority of your larger data files (pictures, videos, documents, etc.) are going to be on the "FILES" partition then 30G is too large for HOME because they'll be very little on it - basically just settings files.

IMO, the best partition setup given what you've offered for information is this:

ROOT ~30 to 40GB and using BTRFS file system.
SWAP ~8GB assuming that's equal to your RAM size.
FILES - The remaining.

Here's my reasoning:
By using BTRFS for ROOT, the 30GB of space will be shared by the Linux OS and your home. BTRFS uses subvolumes to separately contain files so your home would be in a separate subvolume (container) from the operating system. This allows easier backups of home and the OS without having to divide the free space and potentially waste it. With only 256GB drive, you should be mindful of wasting space.

4) Can I install my applications to Home and then keep them intact if the main OS goes down, as just happened? If so, how?

As the same as #1 above, deciding where programs should be installed is not usually up to the user. Primarily because is is assumed that when you install a program all users should have access to it. Anything in your home is only available to you. Also, "keeping them intact" is a misconception. If you have to do a reinstall, you will need to reinstall any programs you added. Any user files that are created by your use of the application will be in your home. Thus, a backup of your home protects what you need. The one exception to this is "appimages" which is a fairly new way to install and launch an application in the Linux world. In this case, an entire application exists in a single package which a user can simply download and run. Even in this case, the application will create files (settings, etc.) in your home folder, but it allows a non-administrator user to install a program.

How do I avoid this?

The direct answer to your question is "Don't buy hardware that doesn't provide Linux drivers", but I suspect you really want to know what to do about it. You can either do nothing and safely ignore them because they're just warnings, or you can research the acpi drivers and see if there's something you can either install or a setting (usually a kernel boot parameter like "acpi_enforce_resources=lax") you can use. Likely, it's totally harmless and just there to let you know that one or more of your acpi features may not be supported. A few minutes of web searching reveals this may be a harmless bug dating to 2015 that has never been addressed because it's not causing problems. I'd just ignore it unless something isn't actually working.

Here's my reasoning:
By using BTRFS for ROOT

Would you recommend BTRFS for all the partitions or just ROOT?

Just root in your case. You wanted a way to share files with Windows and the easiest way is to have an NTFS partition.

Also, I suggest making the SWAP partition at the beginning or very end of the disk. Then later if you want to re-partition for any reason, SWAP is not in the way.

I've written extensively here about BTRFS and how to use it. One of its primary advantages is the use of subvolumes. The *buntu installers will automatically put the operating system files into a subvolume labeled "@" and the home folders into "@home". This segregates the files but allows them to reside on the same file system - which means all the free space is available to either subvolume. They expand and contract as usage requires. Snapshots and backups can be made directly from the subvolumes making rolling back to a previous state and restoring backups super easy.

The only major caveat is that BTRFS doesn't handle dynamically sized files at this time. Those are primarily only swap files and dynamically sized virtual disk drives. So if you are to use BTRFS as your boot file system, a swap partition is necessary and should be created before installation (makes it easier and it's selected automatically at install time). Virtual disk drives for virtual machines (like VMware or VirtualBox) can be put on a different file system or simply made fixed size rather than dynamic.

Once you're up and running, do some reading about BTRFS - here on this forum and on the Arch Wiki pages. You'll be amazed at what it can do.

Welcome to Linux and KFN.

**TwoFistedJustice** · Feb 11, 2019, 04:06 PM

Thank you oshnlvr!

I have done as you said and set up root with BTRFS and everything else as ext4.

I actually don't want to share with Windows. I used to run Windows and only mentioned it because I wanted to have a separate partition for my non-system stuff. And since I don't speak Linux fluently yet, I had to speak Windows. :-) It is my intention to completely drop Windows because I'm sick of my favorite 3rd party apps going unsupported because the developers are sick of MS changing the kernel every two weeks.

I now have my system configured at a base level and need to find a way to back it up for quick restoration should it go boom again. But that's another thread...
