Intel Core i3/i5/i7

[ricomoss]

From everything I've researched there is no hardware support for laptops with Intel Core i3/i5/i7.

Most are able to install but have issues running K10.10 (freezing, graphics issues, etc.). I can't even get K10.10 or K10.04 to install.

I can't find any threads on this forum that address this issue. I'm sure the Kubuntu developers know about this problem but I wanted to post something for others who are having this problem.

It seems if you have a laptop with an Intel Core i3/i5/i7 then Windows may be your only option. I've heard rumors that Fedora 14 might work and openSUSE 11.3 might work. I'm sure there has to be a linux distro that works...I just haven't found one.

That may be true for "everything you've read", but did you read the right stuff?

http://www.phoronix.com/scan.php?pag..._core_i7&num=2

Along with the Intel Core i7 920 and ASRock X58 Super Computer motherboard, we assembled the rest of the test system with 3GB of CSX DDR3-1600MHz memory, 320GB Seagate ST3320620AS Serial ATA 2.0 hard drive, and a NVIDIA GeForce 9800GTX 512MB graphics card. For testing we had used the Ubuntu 9.04 (x86_64) beta with the Linux 2.6.28 kernel, GNOME 2.26.0, X Server 1.6.0, NVIDIA 180.41 display driver, GCC 4.3.3, and was formatted to an EXT3 file-system. The Core i7 processor itself ran fine with Linux, we had not run into any issues, and all four physical cores were detected plus the additional four logical cores provided by Hyper Threading.

Latest version of Linux kernel does support the Intel Core i7 (Nehalem) processors. Nehalem (microarchitecture), developed by Intel Corporation, successor to the Intel Core microarchitecture.

I've tested this CPU with CentOS Linux version 4.7 / 5.2 and RHEL 5.2, Ubuntu Linux 10.4 without a problem.

Conclusion
The Good - Pros
* Excellent performance
* 8MB Cache
* Turbo Boost Technology
* Great overclocking potential
* Price point is fair

The Bad - Cons

* No Hyper-Threading Technology

Here is a technical paper on the topic of MIC's and Linux.

This processor architecture is known as Multi-Core (MC) or Chip Multi Processing (CMP). Any application which is well optimized and scales with SMP will take immediate benefit of the multiple execution cores, provided by the Multi-core architecture. Even if the application is single-threaded, multi-tasking environment will take advantage of these multiple execution cores. 2.6 Linux kernels take instant advantage of the MC architecture. MC also brings in performance optimization opportunities which will further enhance the performance. This paper captures the recent enhancements to the 2.6 Linux Kernel which better support and enhance the performance of Multi-core capable platforms.

DrDobbs published and article by MIT profs that doesn't see any problems with Linux and MC technology.

To get a sense of how well Linux will run on the many-core processors of the future, a group of MIT researchers -- Silas Boyd-Wickizer, Austin T. Clements, Yandong Mao, Aleksey Pesterev, M. Frans Kaashoek, Robert Morris, and Nickolai Zeldovich -- has built a system in which eight six-core chips simulated the performance of a 48-core chip. Then, as they describe in their paper entitled An Analysis of Linux Scalability to Many Cores, they tested a battery of applications that placed heavy demands on the operating system, activating the 48 cores one by one and observing the consequences.

Even Intel mentions Linux as a compatible OS in their embedded uses of the i5 product brief kit.

And those are just a few of the tens of thousands of hits search for "intel i core linux"

Re: Intel Core i3/i5/i7

Ok, it may not be an Intel Core i3/i5/i7 issue, specifically. There are, however, a lot of people with laptops with Intel Core i3/i5/i7 that are having a lot of problems.

Perhaps I should have said:

If you have a laptop with an Intel Core i3/i5/i7 and are having those problems then you aren't alone and nobody seems to have a fix.

Even after reading through your links I still haven't find any suggested solutions to this problem.

The distros that have failed for me so far:
K10.10 - 64 bit, 32 bit, live 64, live 32
K10.04 - 64 bit, live 64
Fedora 14
openSUSE 11.3

The distros that have worked for me so far:
None

Distros I'm currently downloading/trying:
K10.10 alt 64 and 32
K10.04 alt 64 and 32
Mint 32

Re: Intel Core i3/i5/i7

Well, hold your horses. Read Re: Keyboard & Mouse Lockup on Dual-Boot Install W/WinXP Pro. "My i7 is now dual-boot capable. Kubuntu v10.10 64 bit is now installed next door to WinXP Pro and running."

"there is no hardware support for laptops with Intel Core i3/i5/i7."

One must always be careful about specifying absolutes. :P

Re: Intel Core i3/i5/i7

If you are going to quote my post please do so in context.

"From everything I've researched..."
"...there is no hardware support..."

I hold by my original statement since at the time I had not seen any evidence that such support existed.

Now, I have to ask: Why do you guys even post if it's not going to be helpful at all?

Re: Intel Core i3/i5/i7

There was no request for help in the original post. I don't know about laptops, but my desktop i5 runs great.

Simply put, you haven't asked for help. Instead of giving a list of distros that "don't work", avoid the nebulous and give us some meat: errors, logs, specific issues.

If you can't supply those or ask a question, don't jump to conclusions and, better yet, take your post to the Soapbox.

No, I haven't asked a question. This post was not intended to be such.

I've posted questions in more appropriate threads.

Turns out there are no errors or logs because I can't even get far enough into an install to get those.

The only errror I've see is the "i915" error...but that only occurs on about 20% of the installs I've tried.

Again, you have posted useless information. Thanks for wasting everyone's time.

It seems if you have a laptop with an Intel Core i3/i5/i7 then Windows may be your only option.

I don't think that would be an option unless you've got a copy and you're already familiar with it. It's also almost completely proprietary. I've never used it myself, but from what I can see it has a huge learning curve.

I'm curious to see if Mint works. I've had luck with that in the past when I've encountered a hardware problem with Kubuntu. If that fails and you can't find a Linux solution try one of the BSD flavours. I'm a great fan of FreeBSD, you can put any GUI on that you want, and it has a package system just like Kubuntu. Oh, and it runs Linux programs! However, PC-BSD comes with KDE by default. It's also a bit more friendly if you're not used to unix. Good luck.

Re: Intel Core i3/i5/i7

I just booted my work laptop (Dell Latitude 6410, 2.66GHz Core i7) from a 64-bit Kubuntu 10.10 live CD on a USB stick.

Kubuntu loaded fine. WLAN works, sound appears to need a little tweaking but the hardware is detected properly.

It's contradictory.

(In no way accusative - purely investigative!) Back to basics? Do we know that there is a good burn? Do any of these disks work in another machine?

"Top 20 Kubuntu FAQs & Answers" - http://kubuntuforums.net/forums/inde...opic=3099811.0 #1. Installation Issues....

1.a. Installation freezes at xx%
Caused by a bad CD burn (usually), a defective blank CD (sometimes), or a dirty/worn optical drive (occasionally). Linux Live CDs use extreme compression, resulting in the necessity of achieving a perfect bit-for-bit true burn, and an optical drive that reads it with zero errors. So here is the procedure:

- check/verify the md5 sum on your downloaded ISO file against the md5 sum listed for it on the download site (here's how, and here's more)
- set the burn mode to Disk At Once (DAO) mode if it is available
- set the burn speed to 4X -- or the lowest speed your drive offers
- don't even try it with a CD-RW -- they don't work
- if you're still making coasters, try a different brand of blank media or use a different PC for burning
- clean the lens on your optical drive (compressed/canned air might work)
- don't assume that the "Check CD For Defects" function is 100% reliable -- it isn't
- verify suspected bad CDs on another computer/optical drive (is it the CD or the drive that is causing the problem?)
- understand that everyone makes a coaster once in awhile

Have the isos been tried to boot from a USB stick?

Re: Intel Core i3/i5/i7

For what it's worth, I have installed Kubuntu 10.10 on my HP Envy 15-1066nr laptop, dual boots with Win7. This machine sports an i7 quad 720qm - 4 cores/8 threads. I bought it from here, and my brief review is here:

http://www.newegg.com/Product/Produc...-581-_-Product

It booted from the live disk, installed, and booted from first boot pre-updates and ran all eight threads out of the box. Attached is screenshot of me performing post-install updates, and all eight threads pumping away.

I suspect the media is flawed or the optical drive has a problem.

Re: Intel Core i3/i5/i7

I'm running 10.10 on Intel i5 quad core. No problems. I get the same "intel error", but I have ATI, so not related.

Re: Intel Core i3/i5/i7

I think we should just let this thread die. Obviously the OP wanted to have his point known but didn't want any help with his issues.

THE END

Re: Intel Core i3/i5/i7

I think we should just let this thread die.

Without specific information such as motherboard or computer model, there is not much choice... although the original poster appears to have installed linux on other (older) machines, it would not surprise me if, based on the original hardware question, the problem originates from incorrect bios apic tables due to the machine being newer. The tech skills of the OP are an unknown, so newer hardware gotchas can stop anyone other than a person familiar with workarounds.

It shall always be a shame to have a linux user proclaim the only OS option is The Other Guy, which is obviously not so.

So without specific information, case closed.

Edit: Based on other OP posts I'm voting troll.
