I did package the stable client in the past, though: ><https://github.com/bauritcs/opsi-bauritcs/tree/master/x2goclient-bitcs> Nice, but it's opensource and maybe we can make official opsi repo for it with *.opsi packages. Maybe it's a good idea to make it official, like bareos people did it? http://download.bareos.org/bareos/release/latest/windows/opsi/ Some older (4.1.2.0) opsi x2go binaries are in https://o4i.imbi.uni-freiburg.de/public/ repo too.

Fwd: [ArcticaProject/nx-libs] Document compression (#802)
by Ulrich Sibiller 02 Jun '20

02 Jun '20

---------- Forwarded message --------- From: Ulrich Sibiller <uli42(a)gmx.de> Date: Sun, May 31, 2020 at 10:58 PM Subject: Re: [ArcticaProject/nx-libs] Document compression (#802) To: ArcticaProject/nx-libs <reply+ABQHBZHBGIOEJSNWVCG4BAV4372CLEVBNHHBUM3YJI(a)reply.github.com> Cc: ArcticaProject/nx-libs <nx-libs(a)noreply.github.com>, Author <author(a)noreply.github.com> "nopack" in x2go becomes "none" in NX. And it means exactly what it says: do not compress images. This setting saves CPU cycles but required more bandwidth. Images are normally cached this so this is relevant only for the tiem an image must be transferred to the other side. All the things I documented are valid for plain NX sessions (without using x2go but other software). In NX - if you don't specify a compression method explicitly but only a link type - the compression method is derived from the link type. For ADSL you correctly expect adaptive-7 as I listed in the document. Using x2go things are a bit different. The NX code is the same and so are the built-in defaults. For ADSL this is still "adaptive-7". But x2go does always provide a compression type in addition to the link type. So that default is never used but overridden by the compression settings the user specifies in x2go's session configuration. So regarding compression you always get what you select there, in your case it is "nopack" (which becomes "none" at some point because of the internal naming of the parameter). In other words: in x2go you always have to select a clever combination of link speed and compression while using plain NX you can stick with the link speed and use the defaults. If you only touch the link speed setting you will always get 16m-jpeg. I am using an own software for connection (which I cannot make public for legal reasons) and always stick with the defaults. I was not aware of this x2go behaviour. But this might explain why I don't see the performance problems I sometimes hear about from other people. So I consider this a bug. Developers: what's your opinion about this?

Code formatting

Hi, I noticed someone else talking about auto code formatting. Is there a house style? If so is there a recommend formatting tool (I'm currently using Vs code and vi to edit)? Cheers Dave

X2Go Kdrive, current status? Ready for official release?
by Mike Gabriel 27 May '20

27 May '20

Hi Alex, I wonder when would be a good point to get X2Go Kdrive to the majority of X2Go users. I will plan some X2Go work for July and this would be a good occasion to get a new X2Go Server version out containing the X2Go Kdrive wrapper code. What's the maturity status of X2Go Kdrive? Is it releasable? If not, we should get an X2Go server release out anyway and make sure it behaves well, if no X2Go Kdrive Xserver ist installed server-side. What do people think about this?

Hi, now that Melroy and Dave want to spend time in improving x2go it came to mind that we are still lacking a long-requested feature: USB forwarding. So apart from implementing unit tests and doing code refactoring this is a great chance to make yourself immortal ;-) Uli

ICE default IO error handler doing an exit(), pid = xxxxxx, errno = 32, Fedora 32

On Fedora 32 with both MATE and XFCE, X2Go immediately quits with Connection failed.

Bug#1460: possible backtrace
