cymbaloum Posted February 9, 2006 Report Share Posted February 9, 2006 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? [moved from Software by spinynorman] Quote Link to comment Share on other sites More sharing options...
ianw1974 Posted February 9, 2006 Report Share Posted February 9, 2006 What video card are you using? What updates did you apply? Did you apply all normal/security/bug fix updates? Quote Link to comment Share on other sites More sharing options...
cymbaloum Posted February 13, 2006 Author Report Share Posted February 13, 2006 The videocard info from the Hardware manager of Mandriva Control Center 2006.0 IdentificationVendor: Neomagic Corp. Description: NM2360 [MagicMedia 256ZX] Media class: DISPLAY_VGA Connection Bus: PCI Bus PCI #: 1 PCI device #: 0 PCI function #: 0 Vendor ID: 4296 Device ID: 6 Sub vendor ID: 4136 Sub device ID: 145 Misc Module: Card:NeoMagic MagicMedia (laptop/notebook) I performed all the patches and updates suggested by the mandriva software graphical manager (up to last thursday, I think) Quote Link to comment Share on other sites More sharing options...
scarecrow Posted February 13, 2006 Report Share Posted February 13, 2006 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? Quote Link to comment Share on other sites More sharing options...

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...

daniewicz Posted February 14, 2006 Report Share Posted February 14, 2006 Any errors in /var/log/Xorg.0.log or /var/log/messages? Quote Link to comment Share on other sites More sharing options...
scarecrow Posted February 14, 2006 Report Share Posted February 14, 2006 (edited) Section "Screen" Identifier "screen1" Device "device1" Monitor "monitor1" DefaultColorDepth 24 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).
