Hello to everyone!
Hope someone can help me with a little weird problem, as i am unable to find a proper solution in google (well, it is more of a annoyance for me, not problem)
I tend to spend more time on console than in graphical session. Time ago, everytime i wanted to play a game, or surf the web i had to do a startx, untill i installed Slackware, and somehow it could exec SDL programs and games from the console. I didn't know exactly how, i suspect that started a pseudo X session on 8th terminal. It just happened even with a "minimal install".
But now, atracted by the speed and the posibility of a bleeding edge system i installed Arch. Everything is really good, and i will stay here for a long time, but now that i know there is a way to init SDL programs from the console, i want to know how to do it, and save startx just for use youtube (because links -g doesent have java yet).
I installed gpm, and works really smooth. I saw photos and videos using the framebuffer device, can use svga, so it is good in the graphical part. The standard error when i try to start a game or something is: Could not initialize SDL: Unable to open mouse
Any help is welcome!

You need permission to access /dev/input/mouse0 or /dev/input/eventX where eventX is your mouse device. Problem is, permission is reset every time you restart (if you create a special mouse group) so maybe you can add a custom udev rules.

Ah, good taste! What a dreadful thing! Taste is the enemy of creativeness.

Thanks for the fast reponse
As you said it is a problem of permissons, I tried logging as root, and worked. In Slackware I logged as root almost all time, because of lazyness, so this is why i could acces all devices....
I never used udev rules for giving permissons, so im am trying that, i am not very happy to become root just for playing doom. When finding a solution i'll post here.

Ok, as said.
This is how i resolved it:
-created a group called "mouse" ==> #groupadd -f mouse
-added my user to the group mouse editing /etc/group
-created /etc/udev/rules.d/76-mouse.rules (the first number means the priority, i just added a number up the examples, who started with 75, but you can put another one)
wrote in==> #vim /etc/udev/rules.d/76-mouse.rules
KERNEL=="event?" NAME="input/%k", MODE=660, GROUP="mouse"
KERNEL=="mouse?" NAME="input/%k", MODE=660, GROUP="mouse"
KERNEL=="mice" NAME="input/%k", MODE=660, GROUP="mouse"
I restarted the computer as udevadm didnt work, checked that ls -l /dev/input showed me that corresponding devices where in group mouse, and tried zdoom as normal user
And it worked fine!
