I'm just curious about it because I don't think you should need an xorg.conf file.

It would also be nice to know, so we know what to tell other users with the same hardware.

It does work without the xorg.conf.

Wow!, please explain why it's no longer needed and if that goes for other kernels as well. Is it built in or whats different. Thanks, Jerry

FWIW......

It is my understanding that only Nvidia cards need xorg.conf. My Thinkpad (Intel) does not use it and works fine. I recently installed Mepis 11 to a friend's eMachines e-250 netbook (with Intel graphics). It was behaving badly until I found it had created and was using xorg.conf. I renamed that, rebooted, and all was well.

Solve one problem and create another. With the Liquorix kernel suspend to ram no longer works.

Post Re: OpenGL and Intel
I am in the same position with Intel video on my compaq presario C500. OpenGL crashes KWin - sometimes with a recoverable segment fault and sometimes more thoroughly. This is a clean install (with preserved home) of Danum's 32bit "Roadblock" KDE 4.7.4 and sgfxi created an xorg.conf when first run.

Kinfo reports Open GL is 1.4 Mesa 7.10.3 and Intel chipset 94* GM* integrated mobile graphics controller.

I will try the liquorix kernel and report back.

There is also an updated kernel in the Community Repositories. That is the one I settled on and solved the suspend to ram issue as well. But i am also using an updated xorg.conf from squeeze backports.

No. Liquorix enabled partial implementation. I tried the latest two kernels. One allowed a stumbling use of Open GL but still crashed KWin. I have decided to live without some animation because the rest of KDE 4.7.4 seems worth the loss. I have reinstalled Roadblock. EDIT Oops just seen RichB's response. I'll check out that kernel. Thanks very much.

CR Licquorix kernel is installed and KWin does not crash. I just get a message saying that the Desktop Effects change failed and to check my X settings.

Post Re: OpenGL and Intel
I'm having a similar problem. I can't enable OpenGL desktop effects anymore after upgrading Mepis 11 to KDE 4.7. It worked in KDE 4.6. Xrender works, pretty well actually, but I'd like to get OpenGL to work. I've already upgraded to the Xorg from the Test CR, and have run sgfxi but without effect.

When enabling OpenGL, KDE says: "Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values. Check your X configuration. You may also consider changing advanced options, especially changing the compositing type."

Any ideas on what I could do to get it to work?
