- I'm having problems getting the X-Window system to run in colour. I am
- running the 921126 SLS release, Linux 0.86pl5, and XFree86 Version
- 1.0Ya. My VGA card is a Trident 8900C chipset with 512K RAM. The
- monitor is an AAMAZING Super VGA. The computer is a 40MHz 386DX with
- 4MB RAM.
-
- In monochrome mode everything works fine, in both 640x480 and 800x600
- resolutions. I used the standard VESA settings in the XConfig file.
- There is a minor problem in that the text mode is not properly
- restored when I shut down the X server.
-
- In colour mode, I can get a stable image at 640x480, but the mouse
- pointer, windows, and text are all garbled. I also get some "snow"
- when moving the mouse. I can see that xterm and xclock are running
- okay, and the background and window colours are correct, but the
- window borders and characters are not readable. When I shut down the
- X server, I get a totally black screen.
-
- I've tried various options in Xconfig, and turning off shadowing
- of various memory areas in the ROM BIOS setup, to no avail.
-
- The output from startx is as follows:
-
- .no SIOCGIFCONF
- XFree86 Version 1.0Ya / X Window System
- (protocol Version 11, revision 0, vendor release 5000)
- Configured drivers:
- VGA256 (256 colour SVGA):
- et4000, et3000, pvga1, gvga, ati, tvga8900
- VGA256: tvga8900 (mem: 512k numclocks: 8)
- VGA256: clocks: 25 28 45 36 57 65 50 40
-
- I looked at the file tsx-11:/pub/linux/packages/X11/devel/trident.doc.
- It seemed to imply that that driver may assume the video card has 1MB
- of RAM. Could that possibly be my problem?
