?Dear Sir/Madam, I am trying to install Chimera X in the Centos 7 in my local directory. I installed it by converting it chimerax-rc.cpio?. But I cannot launch it, it was showing error about the openGL. Is that because of the openGL or it is not installed properly? Here is the error: WARNING: QXcbConnection: XCB error: 145 (Unknown), sequence: 178, resource id: 0, major code: 139 (Unknown), minor code: 20 NOTE: available bundle cache has not been initialized yet ERROR: ChimeraX requires OpenGL graphics version 3.3. Your computer graphics driver provided version 1.4 Try updating your graphics driver. WARNING: The X11 connection broke: No error (code 0) XIO: fatal IO error 0 (Success) on X server "localhost:12.0" after 668 requests (668 known processed) with 0 events remaining. ? Thanks Gaya
