[X2Go-User] Windows 10 zoom?
Ok so as an admin one of the issues that is beginning to hit me is the zoom issue. Newer laptops have ungodly resolutions 4K displays and they set the max resolution by default with a 200% zoom so that the people can read the text. Now when they start a x2go session the text appears huge. Is there a way to set the zoom different for x applications? ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

Probably not. All those eye-candy DEs (Animations, 3D effects, ...) aren't really good for remote use, anyway, as long as you're using X2Go/NX/X. So it would probably take a diehard KDE fan with coding skills or a paying customer to change that situation. Also, since it works in Debian Buster, there's a good chance it's nothing we broke/could fix, but it's something inside KDE itself (as Ubuntu is based on Debian, but might ship different versions of the packages - depending on which one has the newer packages, it either broke or got fixed with a newer release). > I am afraid that's not possible.

My understanding is that one company already uses KDrive in production, however, they are not using KDE but a differend DE. Gnome3, I think. So feel free to try it, but your mileage may vary. >> Do I really need a full remote desktop, or would it be good enough for >> me to be able to start remote applications in your local desktop? > > I don't know.

Again, be warned that the speed will be comparable to VNC, so if you're suffering with VNC for remote support, X2Go will not really be an improvement - it simply wasn't made for that. Also, using a Windows client to do remote support with X2Go is still pretty buggy. And of course, the server side must be Linux - you cannot "remote in" to a Windows machine. You will have to use VNC or one of the commercial alternatives for that. (By the way, I hear AnyDesk's licensing/pricing model is a lot less complicated and more sane than TeamViewer's, so if you're heavy into remote support use, you might want to check them out - maybe your budget is at least big enough for an AnyDesk license, if you can't afford TeamViewer. On an exactly 0 EUR budget, I guess you will be stuck with VNC for Windows support.)

You are not going to crash it, but you are likely to end up with a black screen, rather than a working X2Go session. Things look better on Debian Buster, from what we hear. So if switching the server distribution to Debian is an option for you, it might be worth a try. Another option: There's a beta version of X2GoServer that you could install, and you'd also need the corresponding beta version of X2GoClient on your Client. This isn't for the faint of heart, so let me know if you want to continue down that route. This new feature is called KDrive. And of course, you should ask yourself: Do I really need a full remote desktop, or would it be good enough for me to be able to start remote applications in your local desktop? If running remote applications is fine, then I would suggest you change the following settings in X2GoClient: Click "Options" in the menu bar, then "Settings". The first tab, "General", should have all the options you need. Check the "Display Icon in System Tray" box, this un-greys the four checkboxes below it, check all of them as well, click "OK". Then, go to the session configuration, and change the session type from KDE to "Published Applications". After that, once X2GoClient is running and has an active session, published apps can be accessed by right-clicking the tray icon and selecting the name of the session. A left click un-hides the X2GoClient window. > I want the server to server to start a new desktop session if needed or use > an existing > desktop session if the specified user is already logged in.

Well, X2Go was not meant as a remote support tool, so while it does incorporate some rudimentary features for that, this mode of operation isn't exactly speedy. Detecting a running X2Go session, suspending it remotely, and then attaching to it is easy, and brings you native X2Go speed. Same goes for starting an X2Go session, suspending it from the client you were using, then resuming the suspended session at any later time from a different, or the same client. Turning a local desktop session into a remote desktop session is a bit hairy. It will not detach from the local console, so keyboard, mouse, and screen on the server side will be active (i.e. other people could snoop on what you're doing, when they can look at the server's screen, or use the keyboard/mouse to do nasty things while you're not looking). Also, as the remote screen will need to mirror everything, it is way slower than a native X2Go session - more like VNC. Again, this is a rudimentary remote support feature, not a "take my local desktop and turn it into a remote session". If you want a desktop session that you can use both locally and remote, I would suggest installing a minimal desktop environment alongside the one you intend to use. Say, OpenBox with Tint2 as taskbar. When logging in locally, use this minimal DE, then start X2GoClient from it, and in X2GoClient, connect to localhost with the session type you want. That way, you get a native X2Go session with the desktop environment of your choice that you can suspend and resume from remote.

So this means either you had a typo when you specified the keyfile, or keyfile authentication, but not ssh-agent authentication, is currently broken on our macOS client. If you want to cross-check, edit the session settings again, and enter /Users/Franziska/.ssh/id_rsa as the file name for the keyfile. Then (this is important) *un-check* the "Try auto login" box again. Next time you try to connect by clicking on the session tile, you should see a pop-up window asking for the passphrase. If you can't log in that way, please let us know so we can start further investigations as to what might be going wrong. Please also note that there is some GUI way of adding your keyfile to the agent, so you don't have to use the ssh-add command on the command line every time. However, since I am not a Mac user myself, I do not know what the proper tool for this is on a Mac. > However, until now (I waited for 5-10 > minutes), I only see a black window instead of a desktop and the > terminal of my server gives me this: [...] > I tried again, and the same thing happens, it connects but the desktop > doesn't load. Before I installed x2go, I did install the KDE desktop on > my server (at least I thought I did, but maybe something went wrong there). Sadly, KDE5/Plasma is a Desktop environment that isn't really a good choice for remote desktop use. The only worse contender is Gnome3 - with X2Go stable, it doesn't work at all, while with KDE5/Plasma, results vary from distribution to distribution. Do you really need a full remote desktop, or would it be good enough for you to be able to start remote applications in your local desktop? If you need a full desktop, I would suggest checking out LXDE, LXQt, XFCE or MATE. All these are known to work with X2Go. If you absolutely need to run KDE5/Plasma, and you can't move away from Ubuntu on the server side (I hear KDE5/Plasma is "kind of" working on Debian Buster), then I am afraid you will need to get your hands dirty - there's a beta version of X2GoServer that you could install, and you'd also need the corresponding beta version of X2GoClient on your Mac (and I'm not even sure if we have macOS beta builds for this particular feature yet). This isn't for the faint of heart, so let me know if you want to continue down that route. If running remote applications is fine, then I would suggest you change the following settings in X2GoClient: Click "Options" in the menu bar, then "Settings". The first tab, "General", should have all the options you need. Check the "Display Icon in System Tray" box, this un-greys the four checkboxes below it, check all of them as well, click "OK". Then, back in the session configuration, change the session type from KDE to "Published Applications". After that, once X2GoClient is running and has an active session, published apps can be accessed by right-clicking the tray icon and selecting the name of the session. A left click un-hides the X2GoClient window. Note that on macOS, at least in earlier client builds, left click and right click did the same (which can be a bit annoying), so it would hide/unhide the client window along with showing the published application list. Not sure if that has now been fixed, as, again, I am not a Mac user myself.
