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

Q: What kind of content do you plan to add to the X2Go wiki? A: I'm not sure yet. I'm interested in looking at the x2go client and will hopefully be able to submit some patches to help out. As I get to know the code and wiki I'm sure I'll find some info I can add to improve the docs.

x2goClient GUI code refactoring
by Dave Chamberlin-Kidd 24 May '20

24 May '20

Hi, I'd like to have a go at bug fixing, tidying up and adding features to the x2goClient and to start with I have spent a bit of time looking at the sessionbutton code to try to get to know it a bit. Having done so I think it would be useful to submit some refactoring patches. Once I've done this, I would then like to take the same approach with some of the other classes (onmainwindow being the next obvious candidate) This is the sort of thing that I can imagine isn't high priority for the core devs but it will, I think, make future improvements much easier to code, review and test. I don't want to stand on any toes so thought I would ask the following before submitting anything... 1: Is the above proposal acceptable? 2: If so is there a particular approach you would like me to take? (my plan is to start by extracting code into smaller functions in a series of small commits) 3: Do the dev team have any other thoughts/suggestions as to things they would like to see as part of a refactoring that I might be able to pick up Just to be clear, to start with my intention is to make the code easier to understand and follow without changing any functionality. Cheers Dave
