Arrow startx fails on Slack 11 - "Failed to set IOPL for I/O"

Hi all,

I have a new installation of Slackware 11 with the 2.4.3 kernel (2.6 crashed) with what seems to me to be a strange problem. When I boot up and startx as root, the X server runs fine until I log out. If I startx again, without rebooting, the screen goes black, with no response from the keyboard or mouse until I reboot again. If I startx as a user ("michael" in this case), which is what I really want to do, startx throws:

Fatal server error:
xf86EnableIOPorts: Failed to set IOPL for I/O (Operation not permitted)

I searched through previous threads in this forum for a solution, and found one that said to give extra permissions to /usr/bin/xinit. However, I had been running into permissions errors with startx before, so I did chmod 777 on /etc, /usr, /lib and other folders that I knew weren't exclusively for root. I now have this guilty feeling that I shouldn't have done that, but I was in a hurry and wasn't sure what to do. But anyway, it seems that I don't have a /usr/bin/xinit to give extra permissions to. Could this be the problem?

Thanks in advance!

Time for a reinstall! works for everyone else so if you want the 2.6 kernel start there and make it work. One thing at a time.

When you have the system installed, create another userid and do things from there. Get used to the idea of not logging in as root and you'll save yourself much time and aggravation.
