Erratic cursor and text display when emacs uses X-window display; Toshiba A305-S6857
Last modified: 2008-10-29 19:21:46 EDT
Description of problem: emacs window suffers erratic display of cursor and
keyboard-entered data. Hardware: Toshiba laptop A305-S6857, Intel
Graphics Media Accelerator X3100. Software: Fedora 10 snap1 installed
to hard drive, updated from rawhide.
Version-Release number of selected component (if applicable):
How reproducible: always with local (laptop) display. Does not occur when
using remote display (different host, different display hardware).
Steps to Reproduce:
1. Start emacs with X-window display.
2. Observe cursor, enter text or use cursor movement keys.
After a short while (less than 30 seconds) the cursor disappears (stops
blinking). It may re-appear some seconds later, then disappear, etc.
When entering text from the keyboard, display of characters typed may
stop. Ctrl-L forces redisplay of window, then the missing characters appear and
cursor display resumes, but the condition is likely to recur a short while later.
No interrupted display of cursor or characters entered from keyboard.

Xorg startup log.
Executed system-config-display, which would not offer the native display
resolution of 1280x800 but 1024X758 at best. Manually configured as a
generic LCD display with 1280x800 resolution, using system-config-display.
Early indication, after reboot, is this has corrected the problem.
I surmise it is the presence of an xorg.conf file, rather than this specific
display definition, that results in superior initialization of the X server.
I shall attach the present, working Xorg startup log so it can be compared
with the original log.
This bug is probably incorrectly associated with component xorg-x11-drv-i810
now, but where it belongs is not clear to me.

No, it isn't
Are you using compiz?
Compiz is part of the Snap1 live image that was installed on this machine,
and the compiz libraries are present. However, "desktop effects"
(System->Preferences->Look and Feel->Desktop Effects->Enable Desktop Effects)
was never selected. Therefore, if I understand your question accurately,
the answer is "No."
"Improvement" reported in Comment #2 is incorrect. The problem continues.
I have a qualitative impression it is less frequent than originally
perceived, but it definitely occurs.
Bug fixed after update from xorg-x11-drv-i810-2.4.2-9.fc10.x86_64
to xorg-x11-drv-i810-2.5.0-1.fc10.x86_64 (or maybe by a change in
a related package). I assume this was an upstream change, and therefore
this report can now be closed.
