(Ascii) second monitor not recognized / graphics card AMD RX560

Hello ,

i have downgraded yesterday from Beowulf to Asciii by performing a clean install (from DVD.iso choosing LXDE + KDE as graphical desktops > now it seems i have a hybrid Devuan smile

on Beowulf both of my monitor were recognized and functioning.

Now on Asciii only one monitor is recognized.

I presume that i am missing some drivers for the graphics card RX 560.

it seems the card is recognized, but something is missing.


lspci | grep 'VGA\|3D'
08:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Baffin [Radeon RX 460] (rev e5)


Please let me know if i need to activate to some non-free repository to install the proper software.



Thank you very much.

Re: (Ascii) second monitor not recognized / graphics card AMD RX560

i was able to solve bis problem by enabling the "contrib" and "non-free" repositories in /etc/apt/sources.list and then updating the package list with "sudo apt-get update"

afterwards i installed with this line from the debian atihowto (under point 4.)

# apt-get install firmware-linux-nonfree libgl1-mesa-dri xserver-xorg-video-ati


the appropriate packages; now the second monitor is active!

thanks!

Great. Such hybrid installs are often problematic. No other issues?

Well, not so much, but for some reason i was not able to switch from LXDE to KDE as Login Manager (with KWin); effectively,
the StartLogin, the Menu was managed by LXQT and the Windows-Display-Manager and FileManager was with KDE (which i very much like, especially the older more responive kde4) -

- so i try to change to KDE altogether, and in the process i ended up performing a new install with Devuan Ascii XFCE.


I really like the responsiveness of XFCE, but for the rest i prefer KDE.


still not sure how to go on with the Desktop Environment; it would be nice to able to switch easier "on the fly" , but this time i was just not persevering enough.
KDE + LXQT is certainly a interesting match (actually i thought that i get a full KDE and a full LXQT, but somehow it got mingled together).

probably this hybridizaion occured because i did choose "lightdm" as displaymanager instead of "sddm" - i did not know that sddm is the one favored by kde. it would be good if upon presented with the option of choosing a displaymanager there would be shown a bit more info on the available options.

Have you tried Trinity? It is in my "to try" list.

I use TDE on a daily basis. It's pretty comfortable and full featured DE even today because KDE and GNOME didn't evolve at all and nobody made anything else comparable with TDE.

Your opinion is important to me. Thank you very much for sharing. I'm using Devuan ASCII with XFCE, but definitely I will try Beowulf with TDE.

tried today the Ascii with KDE, and on top of it i did install TDE 14 (never tried Trinity Desktop before) and i was very pleasantly surprised.
Some things did not function though (printing for example) so i went back to Ascii XFCE, which has been most stable and rapid.
