Created attachment 109035 [details] dmesg Hi I am having issues with a CX700-based machine. First a few words about the hardware setup: the machine has a build-in screen and a secondary screen connected via VGA. xrandr only ever sees one screen though so I'm assuming that they are both somehow connected to the same port of the CX700. Now, if I use the VESA driver I get an image on both screens; since I intend to use the machine for video playback this is not really an option though. If I use the openchrome Xorg driver from Debian wheezy (0.2.906-2) I get an image on the external screen but only distortions on the internal one. If I build a recent version of openchrome from git I get no image on the external screen and something that looks like a C64 game on the internal one (colors are switching back and forth between brown and purple). Also the driver seems to think that no screen is connected. With the old openchrome (and with the VESA) drivers I keep getting this warning from xrandr whenever I (try to) change resolutions: "xrandr: Failed to get size of gamma for output default" I have tried with various resolutions (via xrandr) and different kernel versions (3.2 from Debian stable and 3.16 from Debian backports), lots of log files are attached. Any advice, patches etc. would be appreciated.

Btw, the board involved appears to be an Axiomtek SBC84710, one screen is connected via LVDS (the one which doesn't work right) and the other one connected via VGA.
Hi Stefan, I know this bug report has been open for more than 18 months, but I would imagine that the current OpenChrome (soon to be release Version 0.5 or the latest Version 0.4.188) work. https://cgit.freedesktop.org/openchrome/xf86-video-openchrome/ Here is the detailed instructions on how to install OpenChrome from the Git repository. https://lists.freedesktop.org/archives/openchrome-users/2016-February/007237.html I have a laptop with VX700 chipset, and this one can handle VGA + LVDS FP (Flat Panel). However, due to the way OpenChrome current code is written right now, it cannot handle DVI + LVDS FP simultaneously (this is a high priority feature to implement in the future). You can use ARandR to assign different parts of the screen.
I will change the status of this bug. Feel free to reopen the bug if you think the bug is not fixed.
