Xen console and Xorg very slow

I'm running Xen hypervisor 4.4.1 and the kernel boots up fine. The console is extremely slow and sluggish when drawing multiple lines as well as scrolling applications in XFCE (chromium, word processors, file managers).

I have only one video card in the system, it is an intel integrated gpu on a haswell i7 4790S.

I tried accelmethod uxa in an xorg.conf file which is working fine but does not fix the problem. I don't assume it is an Xorg issue because the console itself is sluggish too.

Is it a kernel option im missing somewhere? the kernel log shows fb0 on bootso it is using framebuffer.

Thanks for any help or advice

Re: Xen console and Xorg very slow

Hey Naruni,

did you solved it? Have almost the same problem, with almost the same setup, playing videos through xbmc.
Already tried to install xbmc directly to the host and also in a xen guest.
When I boot up with the regular Arch boot menu option, everything is fine.

Also tried the same thing with Ubuntu 14.04, with the same results.

Thanks

Hi,

you have to include mulitlib in pacman.conf and update pacman. After that, yaourt will install all missing dependencies.
