Created attachment 38517 [details] [review] fix This patch should fix the issue. Hi, i'v a dell studio 15 laptop with rv620 chipset, i didn't have problem with new pll algo (last d-r-t kernel git,mesa git,libdrm-git,xf86-ati-git), with my internal lvds or external hdmi screen. i think i have add this problem of blue lines at the beginning of new ppl around february, but it was solved: http://bugs.freedesktop.org/show_bug.cgi?id=26358 (In reply to comment #0) > I'm trying KMS on my laptop with an HD3470; if I don't pass new_pll=0 as a > parameter to the module, thin horizontal blue lines flash all around the laptop > screen, both in X and in the console. A screen attached via HDMI is unaffected. What kernel are you using? Perhaps you are hitting the same bug Alexandre which was fixed in a newer kernel. Can you try 2.6.35? I'm already using 2.6.35... (In reply to comment #4) > I'm already using 2.6.35... Ok. Then the patch should fix the issue for you. Can you confirm? (In reply to comment #5) > Ok. Then the patch should fix the issue for you. Can you confirm? Yes, it does (sorry for the delay) |
