Could not set video mode

Hi,

I'm trying to install zsnes on Gentoo Linux. I've compiled zsnes with opengl and png support, have fglrx installed as video driver properly (I have an ATI card), and I've managed to get several games working on my system like GTA: San Andreas, so I think my video config is quite OK.

When I try to start zsnes, i get this:

Code: Select all

$ zsnes
ZSNES v1.51, (c) 1997-2007, ZSNES Team

Could not set 640x480 video mode: No available video device

I tried changing the video mode with the -v option in commandline with no success. (For example -v 15 changed the error message to "Could not set 1024x768-GL video mode.")

Any ideas how I could get it working? I've googled a lot with no success yet...
Thanks in advance.

Are you not running it as the user which logged into the GUI perhaps?

Try "xhost +"?

I'm running it as the same user that is logged in to the GUI.
Tried xhost with any arguments possible, but the error remains the same.
Strangely I can run any other program that uses the X server (the GUI).

Is there anything I need to configure before compiling? I belive the error is because I compiled the source with wrong options. I KNOW it can be run somehow, because I remember playing ZSNES games on my previous OS (Kubuntu) on the same machine, using the same video driver.

Hi again,

after several hours of googling, I've finally found a solution. I thought I should post it, just in case someone else has the same problem.

For some reason, X support is not enabled for SDL by default in Gentoo, so you have to add a USE flag. I think adding the opengl flag might also be useful.

As root, do:

Code: Select all

echo "media-libs/libsdl X opengl" >> /etc/portage/package.use

Then remerge libsdl:

Code: Select all

emerge -vanuN libsdl

Wait for the compilation to finish, then retry running ZSNES.

Hope you find this helpful.
