Subject: [REGRESSION] [2.6.39-rc3] Wrong resolution in framebuffer and X Window
Date: Sun, 17 Apr 2011 16:04:04 +0000 [thread overview]
Message-ID: <201104171804.04664.maciej.rutecki@gmail.com> (raw)
Hi
Last known good: 2.6.38
Failing kernel: 2.6.39-rc3
Subsystem: Intel graphics driver.
Description:
PC should work with 1440x900 resolution. But console (and after) X Window
start work with 1024x768.
I attach dmesg and Xorg.0.log with drm.debug\x14 log_buf_len\x16M options:
http://unixy.pl/maciek/download/kernel/2.6.39-rc1/zlom/kms/
seems that driver cannot detect resolution higher than 1024x768.
Also I boot kernel replace "i915.modeset=1" with "nomodeset" option:
http://unixy.pl/maciek/download/kernel/2.6.39-rc1/zlom/nomodeset/
But then X Window fails to start and got message: "(EE) No devices detected."
Config for 2.6.39-rc3:

Best regards
