Salve a tutti, scrivo per la prima volta su questo sito perchè ho un problema che non riesco a risolvere. Dapprima installando ubuntu 16.04 avevo alcuni problemi in fase di boot del computer, però non ho dato troppo peso alla cosa, anche perchè il problema durante l'utilizzo del computer non era troppo fastidioso (ogni tanto sfarfallava il video durante lo scroll del mouse o il cambio di programma). Diciamo che me lo sono fatto andare bene. Da qualche tempo sono stato costretto ad usare macchine virtuali e ho notato che c'erano errori relativi all'utilizzo delle due schede grafiche che monta il mio computer.

Inserisco qui alcuni dati:

inserendo da terminale: inxi -Gx

ottengo:

Graphics:  Card-1: Advanced Micro Devices [AMD/ATI] Carrizo
           bus-ID: 00:01.0
           Card-2: Advanced Micro Devices [AMD/ATI] Topaz XT [Radeon R7 M260/M265]
           bus-ID: 06:00.0
           Display Server: X.Org 1.18.4 drivers: ati,amdgpu (unloaded: fbdev,vesa,radeon)
           Resolution: 1366x768@60.00hz
           GLX Renderer: Gallium 0.4 on AMD CARRIZO (DRM 3.2.0 / 4.7.0-040700-generic, LLVM 3.8.0)
           GLX Version: 3.0 Mesa 12.0.6 Direct Rendering: Yes

Come potete vedere ci sono due schede grafiche, ora io non sono un esperto per niente, però mi è sembrato di capire che gli errori sono dati dalla seconda in questione.

Provando a verificare cosa mi dava dmesg con:

dmesg > dmesg.txt

ho notato le seguenti righe di errore riguardanti la scheda grafica 06:00.0 (cioè la Topaz XT) nel file di testo ottenuto dmesg.txt:

Quindi ho cercato una soluzione googleandola e ho letto che con il kernel 4.5 i problemi erano stati in parte risolti, quindi ho provato ad installare il kernel 4.5 e ho visto che il video sfarfallava anche di più. Ho provato quindi a passare al kernel 4.7 ma il problema persiste anche se ora da meno errori e di diversa natura:

Spero che qualcuno possa aiutarmi a risolvere questo problema ^^_

Volevo dare ancora questa informazione aggiuntiva ... non ho anche windows in dual-boot, solo linux, in compenso però utilizzo due desktop-environment KDE e PLASMA. Non so se questo posso influire in qualche modo però ho pensato di dirlo lo stesso.
