Hi all,
I have been running Arch Linux on a VIA EPIA EX10000EG with success
using version openchrome 0.2.906, until the upgrade of openchrome to
0.3.0. Since then my screen just comes up blank black.
Trying to get it running, I broke the system and had to do a re-install.
Although, sticking to 0.2.906 would have been the solution...
I have now installed 0.3.1 and still no luck.
The box is booting from the network using NFS and pxelinux. That works
great (much better and stable than I expected!) and gets me into console
mode ok, after setting some viafb properties, on both the DVI as well as
the TV (S-Video) output.
The experiments I have done are as follows:
First I needed to get viafb properly running, so I created the following
options.conf in my /etc/modprobe.d. directory:
|options viafb viafb_active_dev=DVI+LCD viafb_display_hardware_layout=2
viafb_platform_epia_dvi=1 viafb_dvi_port=DVP1 viafb_lcd_panel_id=9
viafb_mode=1024x768 viafb_refresh=70|
This seems to help the viafb to give me a working console in 1024x768
resolution on the DVI output. So far so good...
The drm module is inserted into the kernel at boot. For this I included
the following lines in my mkinitcpio.conf:
|
||...||
||MODULES="nfsv3 via_agp drm"||
||...||
||FILES="/etc/modprobe.d/options.conf"|
...
But, starting up lxdm (X), there is no graphical output on the DVI port,
when I have viafb inserted in the kernel. The screen goes to black with
a static console cursor in the top left hand corner. Using Ctrl-Alt-F1 I
can get to the console, just fine.
I found that leaving out viafb (blacklist it) from the kernel, I start
getting some output on the DVI port. But the video does not properly
sync. I get horizontally and vertically moving garbled lines floating
across my 1920x1080 screen...
The system does not freeze. I can still login using ssh and even,
knowing the keystrokes by hart, I can even login to X (LXDM).
This is my 10-monitor.conf in /etc/X11/xorg.conf.d/:
|Section "Monitor"||
|| Identifier "Monitor0"||
||# HorizSync 30 - 50||
||# VertRefresh 50.0 - 50.0||
||EndSection||
||
||Section "Device"||
|| Identifier "Device0"||
|| Driver "openchrome"||
|| Option "ActiveDevice" "DFP"||
||# Option "TVType" "PAL"||
||# Option "TVOutput" "S-Video"||
||EndSection||
||
||Section "Screen"||
|| Identifier "Screen0"||
|| Device "Device0"||
|| Monitor "Monitor0"||
|| DefaultDepth 32||
|| SubSection "Display"||
|| Viewport 0 0||
||# Modes "720x576" "720x576Noscale"||
|| Modes "1920x1080"||
||# Virtual 3200 1080||
||# Modes "640x480"||
||# Modes "1024x768"||
|| EndSubSection||
||EndSection|
So I figured I should do some further checks, as indicated at
http://www.openchrome.org/trac/wiki/Troubleshooting
Here we go:

Are there any warnings?

Ok. So: some fonts missing, acpid not operational, a lazy manufacturer
and XvMC not supported.
Some other things I tested:
Setting |VBEModes| to "true" sigfaults X...
When I set |Option "ActiveDevice" "TV"|, X no longer checks if there is
anything connected to DP-1 and tells me:
|...

...
But both the DVI and the TV are connected!
I am out of ideas now after having tried many things...
Maybe you can spot an issue...
Thanks for any further suggestions.
