hello everyone,

first of all, i am very impressed by deepin. never been impressed that much by any other distribution in the first place. i hope this impression will stay for a while :-)

after discovering that deepin performs very well on my rather old notebook with intel 945GM i was wondering why it goes completely sluggish (and mad) as soon as i connect an external display.

everything is extremely fluid otherwise and as soon as i connect the cable the whole system hangs and one CPU core is completely occupied by compiz.

is it possible that the drivers aren't configured right?

tried the intel graphics installer (from both deepin store and latest from 01.org) but it told me that the distribution isn't supported, despite trusty generally is.

resolutions laptop: 1280x800, external: 1280x1024

driver output from inxi -G:

Graphics: Card: Intel Mobile 945GM/GMS 943/940GML Express Integrated Graphics Controller
X.Org: 1.15.1 drivers: intel (unloaded: fbdev,vesa) Resolution: 1280x800@60.0hz
GLX Renderer: Mesa DRI Intel 945GM x86/MMX/SSE2 GLX Version: 1.4 Mesa 10.1.3

Kernel: 3.13.0-45-generic i686 (32 bit) Desktop: N/A Distro: Deepin 2014.2 trusty

will be very pleased by any kind of hint where to find that information.

thanks in advance

marc
