Lgogdownloader is a community made helpful program but it does not keep track of time played nor does it unlock achievements.

What really is needed is a Galaxy where at least the eleven most glaring issues have been fixed and then a Linux version of it made.

Yes, i searched earlier and found out what it is. Unftunaltely, just like above mentioned, no time is being measured during gameplay and so on.

You need Galaxy proper for that. I read that at least last week Galaxy did not work in Wine. Go ask for a Linux version in the thread about today's release of the open Galaxy v2.0 beta.

I use it for downloading, I don't need personally to track time in the client or anything of the sort. You can contact GOG and ask when they'll release their client for Linux. But I don't expect them to any time soon. They didn't do it for years and show no sign of new interest to start doing it now.

Slapping together a program that keeps track of time played should be very easy – either fork into a new process and track its runtime or monitor the process list (e.g. via /proc or psutil in python) and use that to keep track of the times.

Updated my system only to be greeted by a black screen... No panic :-)

Things like this is why choosing a distro using more mature versions may be a good choice. Off to find out what went wrong, then pick a suitable fix. Just formatting and installing something I know works would probably be fastest but I would learn the least.

Hmm… Self-installed nVidia drivers?
Usually "black screen" means X server failed to launch on the default terminal. Does switching to other terminals net something? Like, login prompt. If it does, then what does "/var/log/Xorg.0.log" tell?

P.S. My English is awful today for some reason :)

Self installed AMD drivers. I suspected the problem being there too as the system gives no error codes on the motherboard. Will see if I have the energy to look into it later today. Need to start by downloading something for a Live system. I really need more USB sticks so no need to delete the live distro every time I need an empty stick for things like UEFI updates.

Found my problems were at least two-fold with a suspect third, all software related. Two known bugs :-( and one possible screwup by me. At least my screen is not black any more.

Those different logs are insanely long. I suspect deleting them once in a while may be a good idea so you do not fill up your ssd with them.

An interesting question came up. Apparently for a while already GOG started supporting beta versions (through beta release "channel"). I had no idea until now. See:

But it's supposed to be done through Galaxy. So how can Linux users access Linux betas? Galaxy is defunct for Linux releases even on the server side. And I don't see anything beta related on the game download page. Surely, Linux users should be able to access the available release, right?

We can't. Plain and simple.

Why can't they provide betas as regular downloads?

Lately I don't feel like GOG considers Linux as serious platform any more. While I prefer no-DRM shop, lately I'm considering creating steam account finally after all those years... My initial reasons for not using steam are today also mostly invalid, Valve is now basically not a game developer studio any more, and there's some serious competition to it, so the DRM point is the remaining issue I have with steam, but then again their support for Linux is several grades above anyone else, including their investments into proton.

Maybe bacause this is not feasible?
Egosoft typically updates its betas roughly on a weekly basis. And you do remember GOG takes pride in manual validation of uploaded releases for "quality assurance", right? Even if we (or Egosoft) somehow manage to convince GOG not to turn down obvious betas for lots of bugs (seriously, go check their logs for the upcoming 3.0 release), by the time GOG publishes our oh-so-special Linux version it will be obsolete.

I doubt any beta-testing can realistically function with our setup. And it is entirely GOG's fault for not providing Linux any support at all.

Honestly GOG for Linux is a piece of store right now; and I can not see the situation to change "in a foreseeable future". :)
