Hi everyone
First, Congradulation Loki for that News server
pretty cool ! now it’ll be easier to follow the news
Now for the problems :) I've just reinstalled fresh new Debian
(with Voodoo 3 Xserver)… and here what I get
XF86DGAGetVideo: failed to open /dev/mem (Operation not permitted)
When I try to use an SDL application with cluster user. Cluster is
member of the kmem group and /dev/mem is chmod 660 so what’s wrong
? Maybe it’s just me that’s to tired to see the problem but I’ve been
having head aches for about 1 hour now
Anyway :) Thanks in advance for the answer !

open the /dev/mem devices - regardless of the set permissions.
Is this a bug or a feature ?
The only way to get my SDL back to running was to remove write permissions for
normal users from /dev/mem.

I have both 0.9 and 0.10 on my system, using kernel 2.2.11. I can run
fullscreen apps and everything works fine, as any user with 0.9. But any app
built with 0.10 runs into the same /dev/mem problem!!! this is maybe not a
kernel error.

This doesn’t sound good
The problem is even Not fullscreen app doesn’t work anymore as single
user. I’ll investigate on this problem later tonight but it seam strange.
Why kernel block premission to /dev/mem even with write permission for a
group ? kmem group was nice and the fact that I was able to add a user in
the kmem group and use Fullscreen was pretty cool.
Anyone found a way trought it yet with SDL .10 and kernel 2.2.x ?
