ubuntu 14.04 broken graphics driver via additional drivers radeon hd 6250

[serenity nerd]

originally thought mine was the same as the # 1511301 bug so i left comments there about it but after reading through it a bunch of times, mine is very similar but might be different enough that you might want a separate bug report. hope i'm doing the right thing re bug reporting. let me know

i;m amd radeon hd 6250 ubuntu 14.04
so i went into additional drivers for my sound wasn't working, and thought i would try the open source amd driver, but after a reboot everything was all stretched and intensely slow so went back in to additional drivers to revert back but it wouldn't let me do it. it wouldn't let me me select any other option than the open source and then when i rebooted again a manual driver option appeared and wouldn't let me select any other option and the additional drivers page looked different than it had.

when i opened the software updater to get back into additional drivers and it did say it wanted to update a driver in updates so i let it, but it said it failed, but it kept wanting to update even thought it said it already had, and the updates kept failing, and saying go to package manager.

accidentally opened software center and it prompted me to fix problem and then couldn't fix it either and kept opening itself back up again to try and fix it

found the broken package in package manager fglrx-amdcccle and tried to reinstall but got this error in package manager ( E: Internal Error, No file name for fglrx-amdcccle:i386l)

did sudo apt-get -f, but no joy, said there were missing packages.

last thing i tried in terminal before i gave up tonight sudo apt-get install fglrx fglrx-amdcccle

and this is what happened (which looked very much like what happened when i tried to reinstall it in package manager)

this page https://help.ubuntu.com/community/BinaryDriverHowto/AMD said to report issues with 'additional drivers' in the updater in launchpad bugs so i ended up here.

did the ubuntu-bug fglrx-installer but it says it cannot report a bug on a package that is not installed...and around and around i go lol....

HELP! im only a geekling so i've done as much as i feel brave enough to do.

been trying the fixes from https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1511301 but as you can see from my comments there, still no joy. just lots of crashing and graphics issues still.

looks like purge flgrx reinstall suggest in another flgrx bug thread did the trick. screen finally looks and behaves normally. HAPPY DANCES

however sound is still completely gone. that's what sent me in the first place to try the open source driver that crashed everything .. did search through ask ubuntu and found people with different machines all having similar problems with system wide sound issue and no solutions so far. my sound works fine in my windows partition so it's not a hardware thing. is sound a fglrx thing? is this yet a different bug? should i report it as a bug?

thanks everyone for your help and all the ubuntu gods for software creation and sorting bugs and such.

also am afraid to try the open source driver again to possibly sort the sound in case it crashes everything again....
