I upgraded to ubuntu 13.10. Using the non-propietory (tahity, gallium) drivers I got a good result, except that my second screen (a TV) became the login screen.

I installed amd's propietory drivers according to this guide: http://wiki.cchtml.com/index.php/Ubuntu_Saucy_Installation_Guide#Installing_Catalyst_Manually_.28from_AMD.2FATI.27s_site.29_STABLE Yes, I have the right hardware, etc. for that: radeon hd 7950; and there were no (insurmountable) problems before.

I got a normal login screen, but after login a message said that the dual screen config could not be loaded (the total resolution of the screens is too large e.g. if one puts 2 large screens next to each other). Note that there was no such problem with the non-propietory drivers. Instead of a low res screen like the login screen, the screen went black. A black screen, who ever thought of that.

Question is: how do I get at least 1 workable screen back? Please don't assume that I know what code to type and where, or how to get files without a screen.

{I could start a TTY, but sudo startx did not help. I could enter recovery mode, but the menu's this brought up were unreadable.}

{As an aside, I would like to say that I am really puzzled by the fact that dual screens are set up in 2 places: in the settings from ubuntu and in in amd's CCC setup thingy.}

To go to the previous situation, I did: sudo sh /usr/share/ati/fglrx-uninstall

this looked successful, there were no complaints, but now it won't even accept my password.

So, I give up. So much time wasted already.

Edit: ubuntu accepted the new password but won't login with it. Earlier I tried the amd 14.1 beta but it gave a screen of 1200 by 1200 pixels, leaving the remaining 600 by 1200 pixels to the right black.

askubuntu.com/questions/361004/… gives some pointers on the black screen question and the password-loop. Although the upgrade to 13.10 looked OK, I am suspicious about upgrading due to (much) earlier upgrade fails: a clean install via the something other option in the install DVD is quick and may save a lot of time. I tried 13.10 and the new amd catalyst drivers in preparation to a new dual boot setup on an ssd, so the question above is now obsolete. –  Bwog Feb 11 at 12:15
Unanswered questions are: why are dual screens set up in 2 places: in the settings from ubuntu and in in amd's CCC catalyst control centre; if a low-res login screen is available, why not provide that low-res screen to the user after login, instead of a black screen? –  Bwog Feb 11 at 12:15
