After trying to resolve this problem on my own, perusing google etc. for 2 weeks, I could use some help figuring out why I can''t start X11 when booting 2.6.21.7-2.fc8xen on my desktop. Booting 2.6.23.1-42.fc8 and running X11 works fine. I apologize if this is not the right place for this problem, and understand if you think it should be posted elsewhere. Just let me know and I will post it to the email list you think I should be posting to. logs etc. are truncated. I hope that''s okay, I just didn''t want to waste people''s time. lspci out gives: 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35 Express DRAM Controller (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) 00:02.1 Display controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) /var/log/Xorg.setup.log Build Date: 17 October 2007 Build ID: xorg-x11-server 1.3.0.0-33.fc8 (EE) GARTInit: Unable to open /dev/agpgart (No such file or directory) EE) intel(0): Internal Error: maxCacheLines < 0 in i830_allocate_2d_memory() (EE) intel(0): Failed to allocate framebuffer.
