Display problems in some (but not all) applications [solved] : Thanks!

[cymbaloum]

Hello,

 

Like many people, I had display problems when I updated to Mdv 2006 (strange colors, misplaced icons, etc). These issues were sorted out by updating some x.org packages.

 

However I later found out that the issue is not totally settled. When I tried to install some games such as jump'n bump (from plf), and amphetamine (I think), I got back the same display problems (strange colors, multiple displays of the same picture, etc).

 

Well, I don't care about jump'n bump and other small games, the problem is that this also affects my Citrix client, which is critical for me, since it prevents me from working remotely on Linux.

 

Does anybody understand what's going on here, and how to address it?

What video card are you using?

 

What updates did you apply? Did you apply all normal/security/bug fix updates?

Typically MagicMedia 256ZX comes with just 4MB of video RAM, and no option to share system RAM, so you should obviously not expect much from it...

Anyway, the usual solution for color problems with so little video memory is reducing color depth to 16-bit, from 24-bit.

Can you copypaste the part of your /etc/X11/xorg.conf which refers to your video card and resolutions?

It's true the laptop is oldish, but before the 2006 install I had Mdk 10.1 on it and the Citrix client was working fine...

 

Here's my xorg.conf:

Change the last line to

DefaultColorDepth 16

...and then hit alt+ctrl+backspace...

Any better now?

 

(For the record, a quick google search brought up quite a few dispaly problems with that chip when 24-bit color depth is used).

Spot on! Now everything works perfectly!!

 

Thank all three of you so much for the help

 

Next time I'll know where to look when I have these kind of problems again
