[i845G] Kubuntu: Low quality graphics output (needs XAA)

[der_vegi]

Binary package hint: xserver-xorg-video-intel

I have a Dell Inspiron 1100 with Kubuntu 8.10 here, the chipset is a 82845G/GL. The problem is, that X works, but the quality of the output is quite low: Every colour gradient is stepped as it was in 256-colour mode or like in a low-quality jpeg-image. Attaching a "screenshot" showing the login screen on Kubuntu. Note the "rings" starting from the top middle of the screen, this should be a smooth gradient. On MS Windows, the same pictures are displayed correctly.

This also happens with the live-CD of Fedora 10 Preview.

Using xerver-org-video-intel 2.4.1-1ubuntu10.

Same problem here with I830M. At first I thought that it is just caused by the flat panel, but when I opened the same picture in console frame buffer, the problem didn't show up, and the gradient was smooth.

Based on a posting in the Fedora Forums, I edited the "Device" section of my /etc/X11/xorg.conf file from this:

Section "Device"

     Identifier "Videocard0"
     Driver "vesa"

To this:

Section "Device"

     Identifier "Videocard0"
     Driver "intel"
     Option "AccelMethod" "XAA"

For the first time since Intrepid came out, I am able to use the full range of color and screen settings and use the desktop effects fully and without error.

Hope this is helpful to someone else.

Hi,

This will help to get good resolution but still the screen will be blur. Any other suggestions? Please help. I have the similar problem on Intel845G desktop.

Is this still an issue on Jaunty? We're putting a lot of effort into the -intel driver for the upcoming release, and we'd like to send your bug upstream if possible. But first, we need to collect more information. Please report whether the card works in Jaunty, and if not, give the new 2.7.0 driver a shot. It can be found here: https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-updates/

Thanks!
