Still trying with the KDE desktop - every other desktop will boot

[urdrwho5]

I am still trying to get the darn KDE desktop to be reliable.

Can always boot to safe mode
Sometimes it will boot into normal mode
Booting into normal mode I may have access to Alt F2 - commands there can start programs (firefox, etc). Just no desktop

I have Gnome desktop installed and it will always boot into the Ubuntu Gnome desktop 100% of the time
I had Xbuntu XFCE desktop install and always booted into theXbuntu desktop 100% of the time
Booting normally into KDE - maybe 5% (or less) chance of booting into the desktop

Can't try Lubuntu because "The following packages have unmet dependencies:
lubuntu-desktop : Depends: python3-aptdaemon.pkcompat but it is not going to be installed"

I uninstalled the Kubuntu desktop and re-installed but no change.

Nvidia can not work. The problem started with an update two weeks ago. In that update I remember seeing something about nvidia change and 378 (something like it). Now when I install Nvidia and watch the screen while things unpack I do see that nvidia 378 is unpacking. Recommended driver is Nvidia 304.

My wife could live with the Gnome desktop if --- I could get her desktop dolphin picture on it. I installed gnome tweak but still can't get much customization out of it. Oh and a docking panel would be nice. She is even ok with KDE in safe mode. I am the one that it bothers and also knowing that there is something cracked on the system bugs me.

You may be running KDM or GDM, when you should be running SDDM.

For Ubuntu, Linux Mint, and most Ubuntu derivatives:

Run sudo dpkg-reconfigure gdm and select the default display manager in the dialog that pops up. You can replace “gdm” with any of the display managers that are currently installed on your system. If this fails, you can edit the /etc/X11/default-display/manager file with root privileges.

Thanks.

Yes I know that it should be SDDM but when KDE doesn't want to boot, SDDM was not even giving me an option to boot into the Gnome-desktop that is installed. So I had went to LightDM. Still not sure why things are a lot more stable with the Gnome-desktop than the Kubuntu-desktop??

And I've never, ever after many tries gotten Nvidia to work. I think it is that when Nvidia 304 unpackes it also unpacks some of or all of 378.

Your situation is so unusual it causes me to ask what ISO you installed on your hardware FIRST? Did you attempt to add the Kubuntu desktop to Ubuntu, or Mint, or what?

Also, you didn't give any hardware specs so the following is just speculation about the ISO file. Did you verify it with a checksum after you downloaded it. AND, did you verify the LiveUSB or LiveCD after your burned it?

I am running KDE Neon User Edition on a 5 year old Acer Aspire V3-771 and its secondary GPU, an Nvidia GT650M, which cannot be set as primary in the BIOS, behaves like the primary after I installed the nvidia-370 driver. To prevent the problem you had I locked down that driver so that future updates wouldn't break it. In 19 years of using Linux Neon is the best Linux "distro" I have ever used, and I've tested a lot of them.

It all ran quite well for a few months and then sometime at the beginning of February an update came through that did make me raise an eyebrow. It was when I saw something about nvidia update. It was around that time that the video problems began.

Not sure how old the box is but it has

<<2X AMD Athlon II X2 220 processor
6 gig ram
GeForce 6150 SE nForce 430
I think the HD is either 300 or 500.

Has Win 7 OEM certificate inc.>>

I burned a Neon but can't install it because on the one I burned there is no option to start the install using nomodeset. Without nomodeset there is no screen. Running in recovery mode is bullet proof system and maybe I should just go that way.

On the grub screen you can go into the edit mode and add nomodset to the end of the command line.

So what you are saying is that when I want to try Neon I can press e while the live CD is booting and manually enter nomodeset?

In the installed Kubuntu 16.04 I have nomdeset written in grub.

No. I believe that by design, KDE neon Live (CD/USB) doesn't present the Grub menu; it's set to no delay. But, while it's being booted you can repeatedly press the Escape key to get the menu to appear, at which point you then press the 'e' key to edit.

I'll give the esc key a try.

Seems that every flavor of Live CD I've ever tried had a way to start in nomodeset.

you can press any key when the live CD/USB starts to boot and get the screen you are looking for ,,,,,,,with the options to edit the boot line and all that.
