Laptop Video S3 ViRGE/MX low resolution

Asked by mossbarg

I have a laptop (Sager 5100c - NP5120/5130) with which I am trying to run Ubuntu 5.10 Breezy. The video card is correctly detected as an S3 ViRGE/MX chipset. However, I cannot set the resolution above 640X480. The screen is either an LG LP121S2 12.1" TFT SVGA or a Sanyo 12.1" HPA SVGA. The video chipset is S3 86C280-DB.

Running GNOME version of Ubuntu 5.10 w/ GNOME 2.12.1.

This is my first time loading Ubuntu (any release) onto a laptop. Up to this point, all installations have gone smoothly with all hardware detected correctly. Anyone have any thoughts?

try:
sudo dpkg-reconfigure xserver-xorg

See if you can add multiple resolutions.

I managed to get the problem resolved. Reconfiguring XFree86 (xorg.conf) through dpkg reconfigure did not work; however, I did resolve the LCD display problem through a manual edit of xorg.conf. While the problem is not resolved 100% (the login screen needs to be adjusted), I did get X and GNOME to recognize the different resolutions. I set the default to 16 rather than 24 (as 24 is an unsupported setting on my monitor), and I added the vert refresh rate and horiz sync lines. I also eliminated the low res "640X480" resolution in all modes, which in retrospect was probably unnecessary.

Copy of xorg.conf follows with comments on what was removed and added:
