Thanks for the replies and recommendations.
It seems that the best course of action is to stick with the 12.10 version.
I have no issues with it.
Same issue indeed. Running X and setting vga= XXX in lilo will let me switch, but once I exit X, it's game over.
Shutting down the pc from another TTY, while X is still running, does work but seems a bit cruel to my poor little pc ;-)
I prefer getting a different driver to building a new kernel :-)
I have the same problem, but with slackware64 14, here
Sorry, I forgot to mention that I am running slackware64 too.
Can you also find this error in your syslog?
