[KK <1310071@xxxxxxxxxxxxxxxxxx>]

I have a Dell Inspiron 5448 with hybrid graphics: Intel HD 5500u (i7,
integrated) and a AMD R7 M265 (dedicated). I have this same bug. From a
fresh installation of Ubuntu 14.04.2, tried to install:

1.- fglrx-updates from Additional Drivers. Bug appeared and flaky graphics with both cards.
2.- purged/removed fglrx-updates and installed fglrx from Additional Drivers. Bug persisted and flaky graphics still.
3.-  purged/removed fglrx and downloaded the drivers directly from the AMD site (amd-driver-installer-14.501.1003-x86.x86_64). Installed and the bug persisted but it seems that the graphics are more stable now. (no repeated text and no overheating). 

The bug appears specifically when I switch to the Intel integrated
graphics and logout. This doesn't happen when I logout with the AMD
graphics. The bug is also described here
https://community.amd.com/message/1303774 . I get the black screen and
the message "this system is running in low-graphics mode" (sometimes
with cursor, sometimes without).

Whenever I try to logout though, I get the following message (see
picture). No matter how many times I restart and my system is already
updated. The only way to avoid the black screen is to never logout when
using the integrated Intel card.
