*** Bug 470985 has been marked as a duplicate of this bug. *** Ok, I have the same problem on a Thinkpad T61 model 8897-CTO (Intel 965 graphics, 1400x1050 display) with 4GB RAM. Anaconda installed only the PAE kernel (presumably because I have 4GB) and until seeing this entry I hadn't thought of trying a non-PAE kernel, so I filed bug # 470985. Now I have, and it works, so I can confirm that this is an issue with the PAE kernel and I've marked my prior report a duplicated of this one. It seems likely that everyone with more the 3GB and i965 graphics will encounter this when installing F10, so I think this bug should be bumped up in priority. kernel 2.6.27.5-109 appears to resolve the issue. kernel 2.6.27.5-113 has fixed the problem of a blank screen. now when compiz is enabled as soon as I log in, the screen goes white. I'm running on a Thinkpad T61 with and intel 965 graphics. If this is not related, I'll be happy to open a new bug. I get the same thing with compiz, and I also get an X lockup when trying to switch users (i.e. starting a second X server). The lockup looks and feels the same as the one we had on starting the first X server with kernels release < -109. Ok, just to be clear... - With PAE kernel compiz doesn't work, gives white screen and locks up. With regular kernel it works. - With PAE kernel second Xserver (for user-switch) locks up while starting, with regular kernel it works. This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping The latest round of updates fixes this problem for me. I'd say this can be closed. Not fixed, just worked-around. Intel graphics still doesn't work correctly with PAE kernel (for example framerate in glxgears in PAE is about 20% of framerate in standard kernel.) This is certainly an upstream issue, but it should be in Fedora bugzilla to track it. |
Created attachment 321227 [details] Xorg.0.log from PAE kernel Description of problem: If I boot my laptop with kernel-PAE, X starts to probe the hardware but stays blank. In dmesg I see: [drm:i915_driver_load] *ERROR* failed to enable MSI [drm] Initialized i915 1.6.0 20080730 on minor 0 The keyboard is unresponsive as well. The machine is reachable from the network during this. Hardware is: HP Compaq 6710b laptop Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz 4G RAM i965 chipset When booted with a non-PAE kernel, X works fine. Version-Release number of selected component (if applicable): kernel-PAE-2.6.27.3-30.rc1.fc10.i686 How reproducible: Very. Steps to Reproduce: 1. Install kernel-PAE 2. Boot kernel-PAE Actual results: X fails to start. Expected results: X starts. Additional info:
