Dell Laptop Screen Flicker

[anuj seth]

There seems to be quite a few of us trying to fix this problem on Dell Laptops. The problem is simple there is a cursor running bottom to top near the right part of the screen in both ubuntu and kubuntu (7.04). The problem on the Dell Latitude C600(the one I have) goes away on manually editing the xorg.conf file and increasing the wrongly detected resolution from 800x600 to 1024x768. The other machines still have the problem. Such a problem including wrong detection of screen resolution was not present on previous ubuntu releases.

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add your '/etc/X11/xorg.conf' file and your '/var/log/Xorg.0.log' file as attachments to your bug report? Thanks in advance.

this is what feisty auto detects and configures.

[Bryce Harrington (bryce)]

These are two separate bugs. The mis-detection of resolution is a dupe of bug 3731. The screen flicker issue may be a dupe of 122652.

We've recently updated the -ati driver to version 6.6.192, which reportedly fixes other similar screen corruption issues. Can you please check this (either against a Gutsy daily CD, or Tribe5 when it is released), and report whether or not the issue remains?

[anuj seth (greenthunderleaf)]

sorry, but I no longer have this machine.

you can ask some one on this thread i had started a long time back ... the last post which is a week old says the problem persists on gutsy as well.

It's best if those who can see the issue reported a new bug instead. I'm closing this one.
