As some e-mails ago, I'm trying to play beryl in my laptop. I successfully configured my xorg.conf (thanks to the comunity for the help that allowed me that). The problem: When I boot the laptop without external LCD/CRT, beryl is working fine, but when I boot it with the external, it recognice fine the external LCD and don't want to allow beryl run. What beryl says: === BEGIN === $ beryl --test-only ************************************************************** * Beryl system compatiblity check * ************************************************************** Detected xserver : AIGLX Checking Display :0.0 ... Checking for XComposite extension : passed (v0.3) Checking for XDamage extension : passed Checking for RandR extension : passed Checking for XSync extension : passed Checking Screen 0 ... libGL warning: 3D driver claims to not support visual 0x4b Checking for GLX_SGIX_fbconfig : passed Checking for GLX_EXT_texture_from_pixmap : passed Checking for non power of two texture support : passed Checking maximum texture size : failed Root window size (2960/1050) is bigger then maximum texture size (2048x2048) X Error of failed request: GLXBadContext Major opcode of failed request: 144 (GLX) Minor opcode of failed request: 4 (X_GLXDestroyContext) Serial number of failed request: 38 Current serial number in output stream: 40 === END === Searching the web I readed that with "driconf" util I can try to solve the problem. I had installed driconf 0.9.1 successfully, but I don't know how to change that parameters. Does anyone used driconf or knows how can I solve this problem with beryl/compiz?
