Very Computer

I have recently installed the Slackware disks on my Gateway 486 50DX2.
Everything works fine except the virtual consoles. When I switch to
another console using alt-F2, alt-F3 etc. I get the login prompt
but I also get random filled character blocks i.e. at random locations
on the display certain characters will be filled in completely white.
After a few switches between consoles the computer locks up completely
requiring a hard reset. I suspect that the VGA memory is being written
into by some process but I really don't know where to start.

There is nothing "unusual" about the machine. Micronics ISA motherboard
(circa 1990) with Phoenix BIOS, ATI Grapphics Ultra Pro with 2MB, Linux
resides by itself on a Western Digital Caviar 2340 340MB HD. The
motherboard has a 256KB secondary cache.

If anyone has any ideas what is wrong please let me know. Thanks

Hi Mark!

I had the same problems and I solved it rewriting Xmodmap.
Thus you could try to add the following lines in your Xmodmap:

clear mod1
add mod1 Alt_L Alt_R

And for my german keyboard I added:

add mod5 Mode_switch #But I guess, you are using an am. keyboard and
I think you don't need to do that.

I hope it'll work.

Ciao,
Jens.
