I own Dell Inspiron 15R SE (7520) and I have installed Arch Linux on it. It seems that I have two video-cards so I have installed both drivers + Vesa driver (pardon me if that's wrong).

dagrevis@haze ~ » lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Cape Verde [Radeon HD 7700M Series]
dagrevis@haze ~ » pacman -Ss xf86-video | grep installed
extra/xf86-video-ati 1:7.0.0-1 (xorg-drivers xorg) [installed]
extra/xf86-video-intel 2.20.13-1 (xorg-drivers xorg) [installed]
extra/xf86-video-vesa 2.3.2-2 (xorg-drivers xorg) [installed]

When I execute startx, it loads-up, but, sadly, using Vesa. Here's Xorg.0.log.

Why's that? How can I fix it? Thanks!

P.S. I would be happy to use just Intel card and don't touch ATI at all.


After done some deeper reading in log file, I executed:sudo pacman -S xf86-video-modesetting xf86-video-fbdev and installed packages that were missing. Then, I removed Vesa and ATI driver: sudo pacman -R xf86-video-vesa xf86-video-ati and that seemed to did the trick — I'm using Intel drivers. :)
