It might be that we already have KDE5/Plasma support ...
by Stefan Baur 01 Oct '18

01 Oct '18

Hi $LIST, According to Mike#1, who currently attends DebConf in Montreal, Debian 9 + X2Go Stable + KDE5/Plasma have been shown to work together. This is a single report so far, though. If anyone is willing and able to test and confirm this, it would be highly appreciated. Another test result we'd be interested in would be what happens if you use Arctica NX-Libs and X2Go Heuler instead of X2Go Stable.

x2go Windows Client: Strange Issue with Screen Update
by Michael Klemm 10 Mar '18

10 Mar '18

Dear x2go-user list, I'm having trouble with the x2go Windows client on one of my machines. It seems that it misses some screen updates (see the attached screen shot). The screen was made after a I typed "ls" a few times. After I reconnect the session, the screen is updated properly once and then subsequent updates are missing again. This is on Windows 10 Pro (version 1709) and x2go client 4.1.1.1 (nightly build 2017-11-14). The error also happens with the 4.1.0 client. The server is a CentOS 7.4 box with x2goserver-4.0.1.20-1.el7.x86_64, the desktop is KDE. The same client version works perfectly on another Windows machine, so I doubt that the server or KDE is the culprit. If someone could provide me with a hint how to debug this issue to create a bug report, I'd appreciate it. Thanks! Kind regards, -michael

Upcoming Deprecation of (Almost) EOL Distributions
by Mihai Moldovan 07 Feb '18

07 Feb '18

Hi In order to lower resource stress when building packages, I plan to deprecate support for distributions that have (almost) reached End Of Life on December 31th 2017. This includes the following distro versions: - Debian: o 7.0 "wheezy" - Fedora o 23 o 24 o 25 - OpenSuSE o 13.1 o 13.2 o 42.1 Ubuntu builds are ceased automatically after upstream deprecation. After deprecation, no new builds will be published and existing builds will be moved to the archive repositories to discourage users from installing unmaintained software. Mihai

TCE usb mount
by Widu Wittekindt 29 Jan '18

29 Jan '18

Hi again, now that the netboot image builds just fine even on a stretch build host, I have another problem - well I've got a problem for every solution :-) My client doesn't mount usb media, with any of the images I made, regardless of the distribution (stretch or jessie) or the repo (code.x2go.org or LinuxHaus) or the build host (stretch or jessie). But the usb mount works with an image I got from a friend here in Freiburg - but this is a jessie image and one of my clients will not boot with a 3.16 kernel :-( Of course I think I did everything just as I should: 1. put the config as a script in the BUILDDIR 2. put the usb mount patch as a script in the BUILDDIR 3. put the build-script in the BUILDDIR 4. source the config 5. call the patch script 6. call the build script. What am I doing wrong? And theres a second question: Is it possible to output the sound on the x2go-server? cheers Widu

Ubuntu 17.10 x2goserver
by Robert Dinse 22 Dec '17

22 Dec '17

I removed the nightly build and went back to the main line x2goserver and this works except for the xrandr version issue. I still have to set the screen size manually with xrandr -s 1920x1080 but then I can use the entire desktop. It's a pain but at least servicable. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Recent updates to x2go seriously broke it on Ubuntu 17.10. After the update, the first attempt to login resulted in giant fonts, giant terminal windows, giant everything. I went into System->Preferences->Look and Feel and then Fonts, then Advanced and found DPI had been set to 201, set that back to 96 and font size and terminals returned to normal, but I can't use the bottom half or approximately right third of my desktop now. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.
