I am using slackware 10 and have the acecat III. I know it is supposed to work with acecad_drv, when I follow instructions for the driver and change my xorg.conf I end up with a blank screen when I restart x. I am not sure if there is some special config for the acecat III, or whether its the driver. Can someone please help????

Is it a Graphics card?

Give us a bit more information, like if you've enabled anything extra in the kernel or not, what versions of X and kernel you got, what "instructions you followed", what are the errors that come out (the logs)

The kernel is win4lin enabled 2.4.26
I have "nvidia" driver for x
xorg version number 6.7
xinerama going too

some of the instructions

Edit XF86Congif-4:

No logs that I can find.

I got it working with old xf86AceCad.so driver that is built into mouse driver. All I had to do was specify protocol as "AceCad" and driver as "mouse". I had no luck with the acecad_drv for the acecat III. Its an old tablet I spoze. Cheers
