Hi,
I have a problem with a no-name PCI (Union AL23DVGA UTD83A) AT24 card with
1024K display memory.
I tried installing Windows 2000 :p, just to make sure the hardware working
fine, and it could run at 800*600*16bit*85Hz, by the general driver
downloaded from Alliance Semiconductor web site. So I expect it could run X
driven by the general "apm" driver.
Then I started running XFree86 4.2.0, from the binary I downloaded directly
from Xfree86 ftp site. But so far I could only run at 800*600*8bit*75Hz,
with some problems;
1. The mouse cursor seemed always a software cursor, which made cursor area
not be refreshed during mouse action, even when I didn't turn on the option;
2. If I try more color depth, 800*600*16bit*75Hz, the screen will be
blinking;
3. if I try higher refresh rate, 800*600*85Hz, the card will have no signal
output at all.
In case 2 and 3, I tried different monitors, which works find with even
higher bandwidth. And at that time, if I kill the X server and go back to
text mode, the text will be sort of bigger, fuzzy and blinking and not be
able to read, even after reboot the system, so I have to press the PC
hardware restart button to get it back.
I also tried Xfree86 4.1.0 with Mandrake 8.1, and had same result.
Here is graphic card and monitor section in my XF86Config:
Section "Monitor"
Identifier "cv"
HorizSync 46.9
VertRefresh 75
EndSection
Section "Device"
Identifier "at"
Driver "apm"
EndSection
Section "Screen"
Identifier "Screen 1"
Device "at"
Monitor "cv"
DefaultDepth 8
Subsection "Display"
Depth 8
Modes "800x600"
ViewPort 0 0
EndSubsection
EndSection
Nothing under section "ServerFlags" or "Module". I read the 4.2.0 release
notes and "information for AP chipset users", and tried to turn on or off
Option "SWcursor" "noaccel", "nolinear" but no different.
If I put the normal Scanning Frequency range of my monitor, which is
HorizSync 30-54, VertRefresh 47-120, the X server will lock with something
like "Cannot register the mode, please use a slightly different mode" in the
log, or the card just have no signal output.
Here is something might be useful in the /var/log/XFree86.0.log.

Do you have any idea about this situation? Or I have to go back to the dark
Win2K? Thanks in advance.
