I have, in a previous installation of Mandrake, successfully upgraded XFree86 to version 4.4.0 following the instructions in Install.txt and using Xinstall.sh. After upgrading, I changed the driver to "via" in Device Section. XFree started and worked, but I also coudn't get higher vertical refresh frequencies. In fact, I could get 1024x768 @ 75Hz, but my screen is not so big, and I want to use 800x600. These lines are from the VESA log file: (II) VESA(0): monitor1: Using hsync range of 31.00-65.00 kHz (II) VESA(0): monitor1: Using vrefresh range of 50.00-120.00 Hz and these values are correct for my monitor. Using the Via driver, I remember the range was much narrower in the corresponding lines. It seemed to me that was preventing the use of 800x600 at higher frequencies. There were also 4 messages of unresolved symbols in the log file. Well, then I gave up struggling with Via driver. I reinstalled Mandrake and tried to get what I need from Vesa driver. Is it possible to get 800x600 @ 75 or 85Hz from Vesa driver? If not, will you help me putting Via driver to work after upgrading again to 4.4.0? I'm about to give up using Linux because of a flickering screen.
