login loop →fglrx-core (not installed): fglrx-core kernel module failed to build

[Sinisa Radalj]

installed manually as usual but on ubuntu 15.04 first time i get same situation when upgrading to kernel 26 ,and now after cleaning everything for loop after login and that means changing lightdm to gdm and back, reinstaling and resetting unity, enabling compiz unity plugin, do all what need to be done about Xauthority and ICEauthority...and after all those when i manged to have step by step my gui back and to work all like before and that means not using upstart,using light dm,usig unity and compiz ,and unity compiz plugin enabled ,all but again on open source driver and there i pass from lvm-pipe to gallium...so to be clear i get like it was just again i wanted to have fglrx working,and yes i know how to install it manually and so many times i do it/and every time i manage to fix situation one way or other to not do fresh install..

so first time i saw this when i accept upgrade from 3.19...25 kernel to3.19..26 ,so i investigate all those above..to get gui workable even i must restart unity and on screen as user start again compiz,but never mind ..i choose to report this bug-situation as now i know answer and seems its so easy to repet and to recover and more of to avoid that..

  fgrx driver work flawlessly on 3.19..25
kernel update(now i know ,and as so many user i get loop ,i do not expect that i need to back to older kernel.. and older kernel i erase ,remove to not occupy space as usual routine..

so when all other thing works well i try to do from open source to fglrx driver update but i was lazy and i choose to simply do it over gui,add aditional driver..but that finish with black screen too..
over recovery console i purge again fglrx driver ,and prepare all to load install open source driver and voila first on lvm-pipe and then on Gallium driver.. to be litlle bit more complicated this is uefi boot option was diff,more of grphic card not have GOP bios.all lead me to wrong side..

then with all working (in mean time in one of recovery session i do updates as if is some fix let it came..so came newer kernel 3.19...27 and then on that kernel i boot in efi mode without upstart.. on galium and then i try to do step by step fglrx driver manually
but again after reboot i ended in login loop.. and can open other tty 1,2,3,4,5,6 only tty7 and login loop ...well then i check if is same situation without uefi boot,and yes it is..and then in recovery boot i was ready to purge fglrx driver and to go back from kernel 3.19...27 way back to kernel 3.19...25 as i read that is solution ,so this is not and not affecting only me,just i do maybe more aroud this..so to be clear fglrx or fglrx updates was not working on both updated kernel 26 and then 27... but
before i purge both of it ,i simply do as routine update with enabled network and mounted disc in rw mode...so i was suprised
over update came updated version for fglrx-core and fglrx amdcccle.. from revision 1 to revision 2.. so i give that try..

and now my desktop works.. without need to go back to kernel 3.19...25

just if somebody is interesting this is error log when fglrx driver is manually installed/builded for kernel 3.19...27

yes i know that will be problems ,but i choose to investigate as much i can,and seems there is one more thing on list what can cause login loop..
so it not unity,not unity compiz ,not missing signature of still unsupported card,its obvious what is,i learn to not switch so fast to newest kernel..but good news is after same situation ,but not exactlly same reason problems are noted and solution came over fglrx updates ,even in reality i do manual install of fglrx not fglrx-updates.. which crash with previous 26 kernel.. at least i copy situation what was after manual install of fglrx ,and save it,and write easy solution.. maybe will save time to somebody,and sure is interesting..at least in all those thing i remove iommu and install this time fglrx ,well recovery do install of fglrx-updates and overwrite to to even newer sub version,so now i have fglrx working again, and without hardware or software iommu,so i will try again to enable crossfire..what was other real bug..when usb keyboard and usb mouse ,and even networking not working as when hardware iommu is disabled in bios...if previouslly was enabled..or fglrx driver was installed with iommu on,regardless iommu on in bios or software iommu sw in grub config to kernel..well interesting story..next time i will wait one week before upgrading kernel or fglrx updates..lol!

solution: reboot in recovery mode,enable networking,do auto repair,acc. updates ,and somehow fglrx-updates will overwrite and fill what is missing ..even was installed just fglrx not fglrx-updates.. that is only thing what is still strange to me..
