Several strings in Xconfigurator/MonitorsDB for IBM monitors include double quotes to indicate screen size in inches: IBM 2215 15"; 0; 30-64; 50-90 IBM 2248 14"; 0; 30-48; 50-90 IBM 2264-002 14"; 0; 30-64; 50-90 IBM 2264-017 17"; 0; 29-82; 50-150 IBM 6312 14" PS/VP; 0; 31-48; 47-100 IBM 6314 14" PS/VP; 0; 30-60; 50-120 IBM 6318 14" PS/VP; 0; 32-37; 56-87 IBM 6319 15" PS/VP; 0; 30-60; 50-120 Since double quotes are used in XF86Config to delineate strings, this results in unmatched quotes inside XF86Config, which causes X to die on startup.
Will be fixed in next rawhide. Thanks for catching this.
