I am having a similar problem with a gBox system with a S3 ProSavageDDR display chip and VIA chipset on the motherboard.
I have Ubuntu 8.04.1 installed. Here's some lspci info: # lscpi 01:00.0 VGA compatible controller: S3 Inc. VT8375 [ProSavage8 KM266/KL266] # lspci -n 01:00.0 0300: 5333:8d04 In my case, the display chip worked fine with a generic tube monitor, then I was given a Samsung SyncMaster 570S TFT flatscreen monitor. Initially, after that monitor was attached, it displayed a 'display mode not supported' message. (Also I initially had a similar problem with Windows XP - this is a dual boot system - but that was fixed after a bit of fiddling - it worked fine in 1024x768 mode) Ultimately I was able to get the display to work in 800x600 mode, but not in higher resolutions under 8.04.1. I'll attach the xorg.conf file that finally worked - it's pretty generic. Also I tried running knoppix and Mandriva live CDs. These both did work, but with different selections of display drivers. I'll attach the xorg.conf files for all 3 cases. Note that both Knoppix and Mandriva were able to run the display at 1024x768, but one chose 60 Hz and the other chose 76 Hz. I believe the preferred refresh rate for this display is 75 Hz. ** Attachment added: "xorg.conf on feisty - 800x600" http://launchpadlibrarian.net/16540406/xorg.conf.feisty -- [hardy beta] install failure (regression) with ProSavageDDR graphics chipset https://bugs.launchpad.net/bugs/217004 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
