I'm submitting this now manually due to urgency to 14.04 release as ubuntu-bug crashes too ;(
%sudo aticonfig --adapter=all --initial writes a xorg.conf which uses xorg.conf keywords in "text" fields searched by function
static int check_vendor_bus_id_xorg_conf(struct device **devices, int cards_n, unsigned int vendor_id, char *driver)
In line 1072 of gpu-manager.c
"Driver" keyword is found from following lines xorg.conf written by aticonfig
Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection
Line 1119 of gpu-manager.c
else if ((istrstr(line, "Driver") != NULL) && (strstr(line, driver) == NULL)) { failure = 1;
}
Looks the xorg keyword "Driver" anywhere in the line and finds "ATI Proprietary Driver", but of course does not find correct drivername "fglrx" from the same line => Keywords should be searched from the beginning of the line, not all over.
Second issue in same function the format "PCI:%d@%d:%d:%d" which is different to format "PCI:%d:%d:%d" used by aticonfig, which causes misdetection of correct BusID in xorg.conf
If routine "check_vendor_bus_id_xorg_conf()" reports "Check failed" completely valid xorg.conf is overwritten by gpu-manager.c in boot.
Quick workaround for users is to correct the xorg.conf after installation of ATI Catalyst proprietary drivers taking these into account.
This is a bug report against gpu-manager.c in ubuntu- drivers- common.
