I tried to switch on my Lenovo L530 Notebook from Debian testing (KDE) to Arch Linux. Installation was no problem, but when I connect a second monitor to the VGA port the whole system gets very slow / unuseable. (The same hardware constalation works without problems under Debain testing.)
I tried varios things, but nothing solved the problem: - acceleration method: UXA - acceleration method: Glamor - Upgrade to xf86-video-intel-git - Kernel downgrade to 3.14
I tried to downgrade the xf86-video-intel using Arch Rollback Machine but pacman complained about xorg-server X-ABI-VIDEODRV_VERSION. Do I have to downgade the whole xorg? Or should I try to rebuild the old driver which is used in Debian from source against my Xorg installation?
I have uploaded some logfiles to pastebin:

Can someone help me?
