I installed Zenwalk on an old PC, 400mhz Pentium processor, 256MB of RAM, integrated graphics. It works fine, except X restarts when I run terminal.
Everything else is just great, works fast, even GIMP is usable
Now I use CTRL+ALT+F# when I need a terminal, but it's just a temporary solution. dmesg shows no problem.
Any ideas what it might be?
