Title:
Xorg has slow mouse movement when keys held down
Status in “xorg-server” package in Ubuntu:
Expired
Bug description:
On my laptop, when holding down every key except caps lock, shift,
control, and alt, Xorg processor usage goes up by a percent or two
(nothing major) and the mouse position is updated less frequently, to
the extent that it makes dragging things with most keys held down
almost unusable. Since the motion of the cursor is slower in this
state, it is possibly dropping movement events. The system returns to
normal when I let go of the keys.
I ran a couple of tests with X11perf and it doesn't seem to slow down
X in general, just the mouse motion.
My laptop is an iBook G4, which has a powerpc architecture. After
turning off keyboard repeats the problem still remains (even though
xev doesn't report any keyboard events, the mouse movement is still
sluggish until I let go of the key).
This is the keyboard section of my xorg.conf file:
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "macintosh"
Option "XkbLayout" "us"
EndSection
The keyboard is the the iBook G4 keyboard, UK version.
I'm using Ubuntu 8.04, xserver-xorg-core version
2:1.4.1~git20080131-1ubuntu9, xserver-xorg-input-kbd version
1:1.2.2-3ubuntu1, and xserver-xorg-input-mouse version 1:1.2.3-2.
