Title:
[gm45] hotplug interrupt storm when lid is opened
Status in “xserver-xorg-video-intel” package in Ubuntu:
Fix Released
Bug description:
dell latitude E5400, ubuntu 10.10
power-management is set up so "do nothing" is selected for "when laptop lid
is closed" both on ac power and battery power
normally everything works fine, BUT...
while i open the lid, the screen goes blank for a while and the first action
i perform is VERY slow. the screen is blinking for a while, a then it seems to
re-adjust screen resolution (that was already fine). when the very first action
is performed (usually just clicking on a window!) the system works fine.
this is a little bit annoying, buth nothing critical...
the real bug is that SOMETIMES (randomly, i guess), the first action after
lid is open causes the system to be blocked for a few minutes... sometimes 10,
sometimes more.
i can't do anything: the cursor disappears, i can't switch to another
terminal. the screen is not blank, but everything is stuck.
if i log in with ssh, top shows Xorg consuming 80% of cpu. i can kill the
session, but this causes all my opened files to be closed (unsaved!).
this is my ~/.config/monitors.xml :
