Weird graphical glitch issues with multiple distros.
 
I am fairly experienced with Linux and have used several distros. Now however I have a problem that I don't even know how to google.(And I have spent quite some time trying)

I have been running Linux for a while now on several of my machines, but I can't seem to get much of a success rate on my main desktop. Whenever I try to run the live CD with most distros, I get a really weird graphical glitch on the screen. It's almost always the same, just the colors are similar to the splash screen colors.

I believe it is a kernel issue of some kind. As I've said before, I have tried many distros(both x86 and 64 bit) and several kernels. The only ones that I can seem to get working are Ubuntu and Extix.

My hardware is as follows:
Nvidia 750a Chipset
240 GT w/512GB GDDR5
AMD Phenom X4 9850
4 GB DDR2 800

I have tested it with the rest of my hardware unplugged so I don't believe it should be an issue with anything outside of this list.

Any Help would be greatly appreciated.
Thanks!

What is it ? A screen saver ?

bradwhitfield 01-30-2012 07:03 PM

Sorry, I should have clarified. That screen comes up whenever I try to boot into a live CD; I never get to Gnome or KDE. I think it is when Xserver starts. But this happens with both newer and older distors.

Maybe it is framebuffer issue with nvidia chipset ?

Try to use nomodeset kernel boot option when booting ubuntu, use F6 at boot see:

Thanks for the reply. As mentioned in my first post, Ubuntu was not one I had issues with. Following the same ideas however, I was able to get Mageia to boot.(First live CD I found) The problem now is xinit comes back saying "unable to connect to X server: Connection refused." I have had this issue before with other distros as well, it just wasn't as common so I didn't really think much of it. However, this continues to make me think that it's something with Xorg and my hardware.

Thanks for the quick reply!

Perhaps these distros are base on a kernel that doesnt provide support for your videochip. Or you have to install the OS and then go hunting for the right drivers. Ubuntu, mint, and PClinux are know to have lots of drivers already preload, so when you boot they just work out of the box. That is why lots of people like these OSs

But also lot of people dislike all the bells, wisels and graphical tools that these distros come with because advance users find them to "get on the way"

Who knows.

It does shine but isnt gold. Those doesnt work at 100% most of the time, it brings some stable performance but not really well tunned because the generic state as you all already know, and very often little issues with graphics, not distro's fault but they do their best to bring it to us working as good as possible, still, we have to work around if we want the max of our hardware performance.

Thanks guys for the replies and sorry it took me a couple days to get back.

I think I have uncovered the issue. I thought it might have been a patch on a kernel or something. Well, I went through distrowatch.com and found that all of the distros that I can get to work are running the NVIDIA driver out of the box. So it looks like if I boot into text mode to do the install, then deal with the graphics drivers after I get everything installed, I should be good to go.

Just out of curiosity, how difficult would it be to add this driver to a live CD? I know the theory but have not gone about doing it before.

Sometimes custom install for the whole system is the solution for those weird behaviors, the default install doesn't mean everything will work or if will work in the best conditions, and liveCDs are meant to give you a taste of the distro before you install and not to be fully functional. It isn't surprise that many times we have to work around few things to get them working perfectly.

Exactly. That's why I wanted to do an LFS. I just really wanted to know why this happens before I went through all of that work and I can't even use it the way I intended.
