https://bugs.freedesktop.org/show_bug.cgi?id=99851 --- Comment #22 from intermediadc@hotmail.com --- Hi Alex, i made many tests about and understand the issue on 8x slot (black screen with only pulse cursor) probably is gaven by Mesa package. I found this issue on 7750 pratically there when radeonsi is loaded it made the crash of the fence and black screen or totally glitched screen. I will made the same test i had did for 7xxx serie on 6xxx and will see if i will have desktop witout mesa and will report here. in case you can check my tests on 7750 here: https://bugs.freedesktop.org/show_bug.cgi?id=99859#c14 sorry for my eglish is not really good but im try to explain at my best. -- You are receiving this mail because: You are the assignee for the bug.
