Yep, nothing to do with jackd, it's most likely GL shader support. But also? RAM. He doesn't have any! A 1 Gig machine can run that mini-windows edition. It can also run a lightweight linux. But just that. Apps? Plural? No! An App. One. Just like, more than one Firefox tab? Are you crazy?! FreeOrion?! HA!!
OK AK, that's hyperbole except for the last part. It's not that bad, but 1G RAM in 2019 is just bonkers mate. Your phone has more.
I commend you for wanting to put that decade-old Pineview N450 to use, but come on. Be reasonable.
Being that the GMA is on-board and uses shared memory, and that you're running a userspace kernel on MX, likely systemd crap, hald, etc, and then running Xorg with (albeit lightweight) trimmings, gconf, XFCE window manager, some file manager I'm sure, various bits and resident apps and...
Even if you have the 2 Gig RAM version, it's
highly unlikely you'll ever get it working, and if you do, it'll be a prove-a-point kind of thing, it'll never be fast enough to enjoy playing. And your swap will be 8+ Gigs, so just starting a new game could take 20 minutes, depending on how fast the SD card or HDD is. Assuming the OGL support is there. If you're linux savvy, I'd suggest starting compiling your own kernel, but no need to talk about it - if you're savvy you know this, and if not, it's not something to walk you through.
...yea. Those $300 netbook-type things were made for playing videos and skyping grandma and checking emails and syncing itunes and letting you order things off of websites, and that's basically it. Trying to convert them into general purpose computers is an exercise in heartache. Find another use for it. Since you're into gaming, there's a whole subreddit dedicated to putting old hardware to use,
r/lowendgaming... maybe make it into a portable MAME arcade. It's not useless, it just doesn't fit this
particular use.
