I have a Cyrix M II 266 MMX emachine. with RedHat 5.2 installed.
I also just figured out how to install the SVGA version of X to get a
1024x768 resolution.
These directions assume that RedHad 5.2 is installed and the Base X
system is installed.
login as root. Insert RedHat 5.2 cd #1 into the cdrom drive.
# mount /mnt/cdrom
# rpm --install /mnt/cdrom/RedHat/RPMS/XFree86-SVGA-3.3.2.3-25.i386.rpm
Then run Xconfigurator and use the selections listed below
# Xconfigurator
OK
unlisted card
SVGA
Custom
50-70
Don't Probe
4 meg
No clock chip setting
skip
8 bit 1024x768 ( select one and only
one option)
# startx
and I get an aqua background with a control-panel app and a start bar
and a nxterm open.
The biggest trick, I think, was selecting one and only one resolution
setting.
