about the X drivers: with this config, glxgears is running at.... 11fps :-(

which options are you talking about? the boot options?

I'll try the cstate=2 and see if it's OK

the kernel boot options yeh. I include some joggler related options built into the kernel (CONFIG_CMDLINE="acpi=force reboot=acpi intel_idle.max_cstate=2")

then i list options like thermal.psv which can be added to the grub.cfg which can be added to avoid the joggler throttling as much etc.

Archlinux on the joggler with EMGD

Post by cyberic » Sun Feb 26, 2012 8:53 pm

Hello again

I have started another topic since it is only related to EMGD

Thanks buzz, for all the answers you gave

I finally tried to install emgd and it kind of works...

The good news and that the performance with glxgears is a lot better

but:
- the screen is very dark. seems to be backlight issues, i don't know what tool to use to change it
- I had an unresolved symbol in the x server driver:
X: symbol lookup error: /usr/lib/xorg/modules/drivers/emgd_drv.so: undefined symbol: EDID_bin_read

Solution:
add this:
Section "Device"
Identifier "Card0"
Driver "emgd"
BusID "PCI:0:2:0"
Option "PcfVersion" "1792" <- THIS
EndSection

to the xorg.conf

Now it launches, it is dark and the content of the screen is BIG, like if It was displaying only a zoomed portion of the normal screen

I tried to add a 'virtual' directive to the Screen section, it helped a little but it is still not correct

SubSection "Display"
Viewport 0 0
Depth 24
Virtual 800 480
EndSubSection

xdpyinfo gives:
screen #0:
dimensions: 800x480 pixels (212x127 millimeters)

Did you experience this Buzz?

I'm downloading an ubuntu image you made, to get the config files from there.

Thanks again

you dont need to download the image to get my configs - they are here - http://joggler.exotica.org.uk/source/ (overlay tar.gz - including xorg conf with PcfVersion line which also gives correct resolution).

I merged it with the other thread, as it is all the same topic imho (you getting arch linux working on the joggler).

Great! Ok, thanks, that will be far more practical
