Created attachment 369902 [details] dmesg and kernel config file Hello After the kernel loads i915 the console starts in one of the two modes - in the all fonts are blurry o grainy. After starting X11 the colors are distorted (for example, blue is magenta et.) In the second mode, the consol starts to flicker. The fonts and colors are looking normal and KDE session looks good too. The first mode happens more often then the second one. In both cases everything seems to be working fine (except degradeated quality of the fonts on screen) I tried both built-in i915 and load it as a module. I tested both kernel-genkernel-x86_64-3.10.25-gentoo and kernel-genkernel-x86_64-3.13.2-gentoo. I tried acpi=off, does not have any effect Reproducible always Ani advice?

Thank you for reporting, sorry for the late response. If I understand correctly, both 3.10.25, 3.13.1 and 3.13.2 are broken; two questions: 1) Is this still reproducible on the newest kernel versions? 2) Was there an older version that worked?

Hello and thank you for help ad1. 3.14.0-rc7 from March 27, 2014 works perfectly with this kernel I have not seen any flicker nor blurry screen with color distortion using this kernel. So it is stable. ad2. None of the older version I tried ie. 3.10.25, 3.13.1, 3.13.2 and 3.14.0-rc3 did not work. Now I tried to restart 3.14.0-rc3 again and it is still broken (the i915 module is not built in the kernel, I load it as a module so suppose the module is new one from 3.14.0-rc7)

Hello I tried to upgrade my kernel to 3.16.0-rc5 (drm-intel-nighlty from 18th July 2014 ) and it seems the problem of blurry screen is back. The kernels 3.15.0-rc7 and 3.14.0-rc8 are working well.

Hi, Adam, anything new to report here with 3.17 ?
(In reply to Mike Pagano from comment #4) > Hi, Adam, anything new to report here with 3.17 ? Hi Mike I just tested kernel from yesterday (SHA1 240f500cf642ae3a783b6ba97860402f5aeca858) from http://cgit.freedesktop.org/~danvet/drm-intel/commit/ and it is working fine. A few weeks ago (2014-09-02) I applied a patch which solved the problem and since then all later version of the kernel worked for me, see more at https://bugs.freedesktop.org/show_bug.cgi?id=81647 Adam
Fixed in 3.18.
