[14:57] <alkisg> Hi, a school with 18.04 and kernel 4.18 has clients with this card, and they work fine: 
[14:57] <alkisg> VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series] [1002:15dd] (rev c8)
[14:57] <alkisg>         Subsystem: Gigabyte Technology Co., Ltd Radeon RX Vega 11 [1458:d000]
[14:57] <alkisg> Another school has 16.04, and while they launch xorg (I can see it with VNC), they still show the console! I tried updating them from 4.14 to 4.15 and that just made them kernel panic with some amdgpu messages.
[14:57] <alkisg> What would it take to use them in 16.04? Even newer kernel than 4.15? Newer xorg? Maybe just installing 4.18 from the mainline ppa will do it?
[14:58] <alkisg> *tried updating them from 4.4 to 4.15
[15:00] <tjaalton> no idea
[15:01] <tjaalton> newer kernel + mesa probably
[15:01] <alkisg> Thank you tjaalton, will try
[15:01] <tjaalton> or just upgrade to 18.04
[15:01] <tjaalton> 5.0 will replace 4.18 soon
[15:02] <alkisg> I'll give 5.0 and newer mesa a try; upgrading is a bit tricky as they're using multiseat, it's a tricky setup
[15:02] <alkisg> I wanted to postpone that to a clean installation with 20.04 later on
