Hi, 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: dmesg: http://pastebin.com/AW6x11Zq lspci: http://pastebin.com/GQJdJh2F xorg log sna: http://pastebin.com/xmCq1K58 xorg log uxa: http://pastebin.com/j9nH6rHa xorg log kernel 3.14: http://pastebin.com/gijmJnCc xorg log debian: http://pastebin.com/aDR8qHDs Can someone help me? Best regards, Matthias
