Check your logs (sudo dmesg) See if you're getting a bunch of"dump"-looking stuff involving the Intel driver. This was an issue with some of the recent kernels. Fixed in the 4.x versions. I'm running xserver-xorg-video-intel v. 2:2.21.15-2+b2 (latest in testing).

I've seen the Xorg issue somewhere, but fortunately, NOT with any of my instances of MX-14. I'm running either MX-14.4 or its downloaded, updated equivalent on two of my systems and the issue does not show up in either place.

Here is my configuration on this system, which works VERY well!

Code: Select all

Notice that this system DOES have
Graphics: Card: Intel Mobile 945GM/GMS 943/940GML Express Integrated Graphics Controller bus-ID: 00:02.0 Display Server: X.Org 1.12.4 drivers: intel (unloaded: fbdev,vesa) Resolution: 1440x900@60.0hz GLX Renderer: Mesa DRI Intel 945GM x86/MMX/SSE2 GLX Version: 1.4 Mesa 8.0.5 Direct Rendering: Yes

but none of this adversely affects this system - at least with MX-14.4 and the 3.14-0.bpo.2-686-pae i686 kernel.

However, I think it is my pure Debian Sid image, which rarely experiences issues, which was recently absolutely sucking CPU cycles and performing uncharacteristically poorly. Next time I get a chance, I'll do a dist-upgrade there, and if it doesn't resolve itself, I'll use the smxi tool with sgfxi to rebuild the graphics driver and maybe that will help, plus I'll get the latest kernel as well.

Thanks for the notes on this!
