Hi Adhefe,
welcome! Thanks for taking the time to join and post. Mageia is a great community. I hope you enjoy it.
For a proper introduction, you can introduce yourself over at:
https://forums.mageia.org/en/viewtopic.php?f=2&t=15I know there are often GPU driver issues: I'm not sure what your problem is, but it would be great if you could note it over at 'the pad' where the QA team (quality assurance) make their notes, and the developers can check it out:
https://pad.riseup.net/p/mageia7-beta2 The top of that page tells you what to do, it's pretty simple, and any information you add is really appreciated.
*note: that address changes as the releases trickle out: So the best way to know the current one is to check out the QA irc channel: #mageia-qa and the title/info has the latest info regarding testing/QA.
If you do ever have time, all the mageia irc channels are pretty good places to hang out. Unfortunately, the spammers attacking IRC mean you need to be registered, which isn't hard, but it seems to have driven people off IRC, so you may not get an instant response, but people will be around: The mageia community, is spread across the globe.
It's a shame it didn't boot for you, but Mageia 7 is looking pretty amazing already.
