Hello,
We are exploring an option of using Wyse C50LE terminals as Citrix workstations. These devices are based on VIA C7 CPU and feature the VX855 chipset.
I have been unable to get the X server to work. I have tried loading the "xf86-video-openchrome" extension, but the "sudo Xorg -configure" generates the following error:
open /dev/fb0: No such device
Number of created screens does not match number of detected devices.
Attached is the full Xorg.log
My "onboot.lst" looks like this:
Xorg-7.6.tcz
Xprogs.tcz
Xorg-7.6-3d.tcz
xf86-video-openchrome.tcz
I am reluctant to use VESA mode which I think would work. Please advise.

Last doesn't seem to make sense. Please rephrase.
From attached log it appears like support for 3 cards has been requested...

Hi tinypoodle,
thanks for your reply. What I meant was that I would like to use Xorg-7.6 as opposed to Xvesa. I tried using Xvesa and it does work, although the resolution seems to be limited to 1024x768. I need support for 1280x1024 per monitor on dual screen machines.

Hi mbrijun
I'm running Xorg7.5 on my machine because Xorg7.6 would not work with my hardware. Just a thought.

Does that apply for both Xvesa.tcz and Xvesa-7.1.tcz or not?
-
tinypoodle: I have only tried Xvesa so far and the result was 1024x768 max resolution. I will try Xvesa-7.1 later on.
rich: Thanks for the idea. I do get graphics with Xorg-7.5, however just like with Xvesa, it is limited to 1024x768. I suspect it might be having issues with the "unichrome" driver that ships with Xorg-7.5.
I am close to throwing in the towel and advising my boss not to buy these devices. I tried booting it from a recent Xubuntu live CD and the graphics is just as bad, at 1024x768 max. However, the Xubuntu has the same version of the "openchrome" driver as TC 4.5, which I believe is 0.2.904 (or something similar).
Before giving up I wanted to try the latest "openchrome" version 0.3.0. I installed Xorg-7.6-dev and tried compiling the driver, but was informed that the "make" command cannot find "xf86.h" header file. I checked and the file was present. Could anyone please tell me how to best resolve these path issues? Would it be the "-I" option? Or perhaps someone would be kind enough to compile this driver and put it into the repository? ;D

Hi mbrijun
My Nvidia driver would not give the correct resolution either, I had to do this:
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Virtual 1920 1080
Depth 24
Modes "1920x1080"
EndSubSection

my biggest problem is that the "sudo Xorg -configure" fails without a fail (pardon the pun). I am unable to extract a consistent "xorg.conf " which I could then modify. I assume I could place the "Screen" section under "/usr/local/share/X11/xorg.conf.d" but not sure if this will work.
-
Hi mbrijun
According to the Xorg documentation, xorg.conf.d will accept a Screen section.
-
If you need a template, you can copy the xorg.conf.vesa shipped and edit it to load openchrome.
-
When you boot with code "vga=ask" and then when prompted enter "scan", what is the highest resolution offered?
Doing so may also create /dev/fb0 and remove the related error from Xorg, so you could try again to configure from scratch.

Hi,
sorry for the lack of an update... I have temporarily put this project aside. Hopefully will have some time next week to look into it.
