Hi- I am a software engineer working with a VME Single Board Computer with a "CT69030" running Redhat Linux 8.0, which appears to be utilizing XFree86 4.2.0 (by examining the install log). I am experiencing difficulty changing the resolution settings. The original driver that was delivered with the system was called "chips" which would cause a complete system freeze (no mouse or keyboard input) within one minute of starting XWindows (using the "startx" command). Since that time- we have reverted to a generic VESA driver- which fixes the system crash- however when I attempt to change the resolution to anything higher than "640x480", log out, then log back in, I lose the bottom half of my screen, and I see no difference in the screen resolution. Big mess! Contrasting to Windows, when you increase the resolution, the icons get smaller, and everything fits on one screen. This is what I am trying to obtain in the Linux environment, as I am trying to run a graphically intensive program that does not support. The SBC Vendor has informed me that there is a known hardware problem with this video driver in a Linux environment, but that there might be a patch available in later versions of the driver. Does anyone know if this problem can be resolved by migrating to a later version of XFree86- or should I really be looking at a new SBC. Please reply and let me know if you can provide some assistance in this regard. Thanks, Andy |
