Slax has always had xorg problems, I Don't know why these problems were not solved. It would be a good distro if these problems disappear. When I Use slax and do things such as coping or deleting a lot of files on a partition that is not the slax one xorg crashes and sometimes the screen flicks with the cursor that go where he wants. Have you ever noticed this problem?
The graphics problem that you are experiencing might be because xorg in slax 6 is too old :(
Have you tried the latest drivers, ie., download them from slackware-current and lzm'd them?
You can't complain too much. Have you donated to slax project? If you have, then you have right to complain and ask Tomas for help, but if you have not then you are on your own my friend.
I don't have a credit card as i'm only 16 years old (almost 17). I know that to keep this domain online costs money, I'd like to help but I can't. I'm not complaining but I'm reporting an issue and asking for help to know how to fix it. well I'll try to do what you said, I'll download the xorg server and update it. what are its dependencies
