[Bug 442395] Re: X segfaults with radeon driver - VidModeGetFirstModeline
*** This bug is a duplicate of bug 300310 ***
https://bugs.launchpad.net/bugs/300310
Although applying http://bugs.freedesktop.org/attachment.cgi?id=22595
which I am assuming is the same as 157_check_null_modes.patch, does stop
X segfaulting, apps that used to segfault X now just don't run at all.
For example winecfg gives
X Error of failed request: XF86VidModeExtensionDisabled
Major opcode of failed request: 134 (XFree86-VidModeExtension)
Minor opcode of failed request: 6 (XF86VidModeGetAllModeLines)
Serial number of failed request: 82
Current serial number in output stream: 82
The problem seems to be that for some reason pScrn = xf86Screens[scrnIndex]; is returning an empty list of modes. Any ideas how to address this underlying issue?
