Just upgraded to (latest stable) gentoo-sources-2.6.32-r7 and xorg-server-1.76. As is often the case, some component is not ready for prime time. About five seconds into a kde login, the screen goes blank with the following in /var/log/messages: Apr 9 14:15:18 system kernel: [ 33.202885] render error detected, EIR: 0x00000010 Apr 9 14:15:18 system kernel: [ 33.202893] [drm:i915_handle_error] *ERROR* EIR stuck: 0x00000010, masking Apr 9 14:15:18 system kernel: [ 33.202904] render error detected, EIR: 0x00000010 Apr 9 14:15:34 system kernel: [ 49.230006] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

Did you rebuild all the modules against the latest kernel? If you're using portage-2.2, make sure emerge -pv @module-rebuild doesn't list any packages. Also, since this is about the intel video driver, can you test with kernel 2.6.33? I had a few issues here when moving from X to VTs and back that were fixed when I upgraded to KDE-4.2.2 and gentoo-sources-2.6.33.
(In reply to comment #1) What modules? I basically always attempt to build non-modular kernels. If you mean xorg modules, I did rebuild the two drivers (evdev and intel), but nothing else (the upgrade did consist of twenty-six packages in total). Not using portage 2.2. Regarding systems, reliability is the most important factor to me. I run stable gentoo, and expect not to run into problems like this as often as I do. We just got the first 2.6.32 stable kernel yesterday (and people kept telling me that that would stop gpu hangs). Did you mean kde 4.4.2 (instead of 4.2.2)? While I am eager to see something in the 4.4 series go stable, time and system constraints make it difficult for me to install and manage unstable versions of kde.
Not a KDE issue.
