Bug Description
SRU Justification:
Impact:
Binary package hint: linux-image-
hardware HP ProBook 4510s (has HDMI)
Kernels without bug: 2.6.31
Kernels with bug 2.6.32, 2.6.33, 2.6.34, 2.6.35, 2.6.36rcx (including standard ubuntu and vanilla kernels) Ubuntu Lucid installed, and Meerkat Beta booted from USB-stick)
Bug also occurs in opensuse and fedora
Bug also occurs with KMS disabled
Driver i915
graphics Intel 4500 GMA, display 1366x768
Description of bug
Sometimes the mouse pointer or windows seem to disappear at the right side of
the screen after login or after CHVT
A print screen reveals the bug very clearly, see attachments (the mouse pointer
and nautilus are invisible, I only see the left image).
Executing xrandr (without any or with options) will cure the desktop
I attached a xorg.0 dmesg with boot parameter drm.debug=0x6.
I patched the kernel with the patch included in this report to kernel 2.6.32 and 2.6.35, this fixed the bug. I did not find any side effects.
I reported the bug at kernel.org, see https:/
If you need further information, please let me know, but I am not a Linux
expert
Kind regards,
Otto Meijer
Fix:
Application of an upstream commit.
Test:
Apply the patch, test the kernel and see if issue is resolved.

The patch has been applied to the drm-intel- next-queue. I applied that commit and am making test kernels available at http:// people. canonical. com/~bradf/ lp638939. There are kernels for Natty, Oneiric and Precise. Please test the appropriate one for your system.
