This is probably a duplicate of bug #78681 Fixed in 3.16(.2) |
Created attachment 141221 [details] Dmesg with 3.15.2 (corrupted display) When trying to boot with 3.15.1+ (Arch Linux), the display becomes corrupted, displaying green lines. After a few seconds (probably when X starts), screen becomes black. Beside display, computer boots normally and can be reached with ssh. The computer is a Sony Vaio SZ6WN/C laptop, with a Intel 965GM graphics chipset. The secondary video card (Nvidia chipset) works properly. Latest working version tested was 3.14.6. 3.15.0 remains untested.
