Public bug reported: Binary package hint: linux-image
Kernel 2.6.32-19 ignores the lid status which is bad if you use your notebook with a docking station and an external display. Kernel 2.6.32-18 or older and the mainline kernels handle a closed laptop lid like a disconnected LVDS display. Since kernel 2.6.32-19 lucid boots up with a wrong diplay resolution because both displays a switched on even if the lid is closed. The displays are mirrored and switched to 1152x864 instead of their native resolutions. This leads to a blurry and warped GDM. a...@xyz:~$ uname -a Linux xyz 2.6.32-19-generic #28-Ubuntu SMP Thu Apr 1 10:39:41 UTC 2010 x86_64 GNU/Linux a...@xyz:~$ xrandr -q Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) LVDS1 connected (normal left inverted right x axis y axis) 1440x900 60.0 + 50.0 1360x768 59.8 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 DVI1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 434mm x 270mm 1680x1050 59.9*+ 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 TV1 disconnected (normal left inverted right x axis y axis) a...@xyz:~$ uname -a Linux xyz 2.6.32-02063209-generic #02063209 SMP Wed Feb 24 10:09:53 UTC 2010 x86_64 GNU/Linux a...@xyz:~$ xrandr -q Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) LVDS1 disconnected (normal left inverted right x axis y axis) DVI1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 434mm x 270mm 1680x1050 59.9*+ 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 TV1 disconnected (normal left inverted right x axis y axis) ** Affects: linux-meta (Ubuntu) Importance: Undecided Status: New ** Tags: lucid -- Kernel 2.6.32-19 ignores lid status https://bugs.launchpad.net/bugs/555131 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
