package: x2goclient version: 4.0.3.2-0x2go1
Hi,
When starting X2GoClient in fullscreen mode on a Raspberry Pi (running Raspbian 7.8), the X2GO logo that appears on the black startup screen is shown in green rather than in the usual grey.
Also, when running LibreOffice Impress, things look OK while composing a presentation, but switching to presentation mode, the colors are wrong again.
This may be related to a color depth setting somewhere? IDK. Would love to hear other people's ideas and opinions as to how to find out what's going wrong. A sample system where we can try out things is available, it has been donated to the project by the Niuco company.

I just checked the color depth of the X2Go session on the Pi by running x2golistsessions: 12596|x2go-gast01-50-1428670060_stDLXDE_dp16|50|x2gotcsrv|R|2015-04-10T14:47:40|862605e06e24b10f9a7c3ec25dd4846b|192.168.133.10|30001|30002|2015-04-10T14:47:41|x2go-gast01|62|30003|
So it seems we're running in 16-bit color mode on this particular Pi.
On the Pi itself, the kernel parameters were: dma.dmachans=0x7f35 bcm2708_fb.fbwidth=1824 bcm2708_fb.fbheight=984 bcm2708.boardrev=0xe bcm2708.serial=0xe6ae45f7 smsc95xx.macaddr=B8:27:EB:AE:45:F7 bcm2708_fb.fbswap=1 sdhci-bcm2708.emmc_clock_freq=250000000 vc_mem.mem_base=0x1ec00000 vc_mem.mem_size=0x20000000 dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 elevator=deadline root=/dev/mmcblk0p2 rootfstype=ext4 rootwait
So while I see parameters for framebuffer height and width, I can't see anything specifying the color depth.
Is there any place where I can force it to use 24/32-Bit color?

Dear Stefan,
the GPU memory is defined in the file /boot/config.txt. The bios on ARM computers is on the boot file system. I add here the parameter at the end of the file /boot/config.txt:
gpu_mem=128
You can do this with your favorite editor, or use
$ sudo raspi-config
-> 8 Advanced Options
-> A3 Memory Split
I think 128MB is the max, if your system has only 512MB memory.
Full HD resolution is 1920 * 1080 = 1,966,080
and this number * 24bit colour = 47,185,920.
I am not an expert with graphics but I think you should have all colors.
There is another thing that I would like to mention. I one of the latest x2go reports I saw the keyword DEB_DISTS_SUPPORTED="raspbian"
Please do not use raspbian, because it is not suitable for professional X2Go support. Raspbian is very nice and great, but too much software is part of the package.
Now I use Minibian (can be downloades from http://sourceforge.net/projects/minibian/ )
This is much smaller than standard Raspbian and you do not have to uninstall so
much software. On the other side it is compatible with Raspbian.
Only this change is needed in file
/lib/udev/rules.d/75-persistent-net-generator.rules
and change here at line 20, “device name whitelist”, to this:
—–
# device name whitelist
KERNEL!=”ath*|msh*|ra*|sta*|ctc*|lcs*|hsi*”,
GOTO=”persistent_net_generator_end”
—–
And then delete the file /etc/udev/rules.d/70-persistent-net.rules
This is needed so that the system always generates a new eth0 device.
The most professional supporter for X2Go on the Raspberry PI is Gibbio. I do not know more about this person. He uses standard Debian SID with X2Go and you can see the announcement at http://rpitc.blogspot.de/2015/02/testing-raspberry-pi-2-thinclient-with.html
You have to think about it, that on the Raspberry Pi you have Debian, Fedora and Ubuntu and many more operating systems. And as I see it on the X2Go doc page, all of those operating systems are supported.
I think the difference between Debian Wheezy and Debian Jessie is much bigger then between Debian and Raspbian.
I also think the different window manager like lxde and xfce make it also difficult for developers. So why care about Raspbian. There are so many armhf devices coming out, like the Banana PI or the Orange PI or all the other clones.
Have a nice weekend, Franz Lückl

I've tried appending the parameter to the existing last line in config.txt, as well as placing it in a new line. Same result.
Haven't tried your suggestion "Minibian" yet.

Hi Stefan,
I checked my system with x2golistsessions and I get: 29055|fraroot-50-1429097497_stDGNOME_dp24|50|srv01.wearenot.net|R|2015-04-15T13:31:37|fce90bf57015643ac8c7f7e46183688d|88.69.19.123|30003|30004|2015-04-15T13:31:40|fraroot|516|30005|
So for me this is 24bit. But I am using X2Go only in a window with a resolution of 1440x900. My x2goclient version is 4.0.3.2-0x2go1. Full screen does not work with GNOME desktop and x2goclient on Raspberry.
And here the output from the startup: NXPROXY - Version 3.5.0

You can use my X2Go servers on the net to make extra testing.
Is there a way to check the color deepness on the X2Goclient side?
Is there any guideline that says you should use this graphical desktop on the client and this graphical desktop on the server?
Have a nice day, Franz Lueckl

For my tests, I used grep -i depth and grep -i bpp
on /var/log/Xorg.0.log

There are some unsupported desktops on the X2Go server. The compatibility list can be found here: http://wiki.x2go.org/doku.php/doc:de-compat
I haven't heard about client-side desktops being incompatible with X2Go. Please file a bug and provide relevant data (Linux flavor and version, X2Goclient version, repositories used, ...)
