I have some problems with Fedora 12 and the main is I can notice flickers on my notebook LCD.
I have checked with xrandr - it shows 60 Hz - in the output everything like in opensuse.
But I do not see any flickers on opensuse, I see them on Fedora.
I was trying to turn off TV1 and VGA1 - did not help.
I was not able to change uxa driver to something else, like xaa or exa, may be that can help. It looks like vertical refresh is not 60Hz, or may be not always.
May be some one can help me with it, some pages, or bugs about it.
Because I can't use fedora longer then one hour, I start to feel pain in my eyes.
Driver i915, for Xorg - uxa, refresh rate and size 1024x768 65Hz. Everything the same with opensuse, but looks different.
Sometimes, when I do not look directly on screen, but on keyboard or near, I can notice picture a little bit flickers. I have never notice it before.
Checked this - did not help. And it looks like, I can't anything except UXA, I did not found way how to tell X11 use xaa or exa.
I also was unable to disable DRI2, X11 still use it, "even it is disabled by default"
Need help - how to disable DRI2, I want to check difference. I do not have it in opensuse 11.1
After 4 hours I can notice flicker on first blue screen with logo "F" within boot time.
Looks like it is not problem with X11 and its drivers.
Anyway - the result is I can't use it.
Strange, but I've never experience anything like it on suse 11.1 - but it uses different kernel. I will check their LiveCD with the same kernel and post my opinion.
