This GPU is not detected for proprietray drivers installation in Softwares & Update section.

AMD has given the drivers only for 14.04.5 LTS and depends on xorg version of that time 1.1x also Linux kernel 4.4

Is there a way to rollback to that xorg version & use the same driver on 20.04 installation.

A guide would be of great help..

Currently im using the iGPU Intel HD Graphics 4000 MESA GT2..// Radeon 7670m is shown & is inactive. i solved screen tearing with intel.conf file in xorg.

I am also ok with using 14.04.6 LTS now without support, But a guide for setting all ppas or apt repo for getting most recent softwares with dependency restrictions..would be of great help.

  • Run DRI_PRIME=1 glxinfo | grep OpenGL and you'll see that all is working. You don't need any drivers. – Pilot6 Jun 18 '20 at 20:24
  • Now AMD drivers are integrated into the kernel and work quite well. – Pilot6 Jun 18 '20 at 20:27
  • I have intel.conf for xorg screen tearing set up , i would like to switch to radeon , by updating grub im not 100% sure about a working tutorial.. – bCi Jun 18 '20 at 20:42
  • You can't "switch to radeon". You can run any application you like with radeon using DRI_PRIME=1. – Pilot6 Jun 18 '20 at 20:46
  • I hope adding DRI_PRIME=1 in /etc/environment & restarting wont cause a conflict with xorg and intel conf. – bCi Jun 18 '20 at 20:52
  • Why are you worried about intel.conf? It is unrelated. – Pilot6 Jun 18 '20 at 21:14
  • I have set intel.conf file for xorg to resolve screen tearing. previously using a radeon.conf stopped system from booting and i was into root terminal. To login. .. i guess i need to blacklist intel graphics and set radeon=1 some where in etc and change to radeon.conf for xorg config. Note running DRI_Prime = 1 is still iGPU in my case i guesss – bCi Jun 18 '20 at 21:27
  • No, you don't need to blacklist anything. DRI_Prime != DRI_PRIME. And why would you want to run everuthing on radeon? You are doing weird things. – Pilot6 Jun 18 '20 at 21:55
  • I deleted 20-intel.conf file in xorg.conf.d and screen tearing is back again, this time i am able to see AMD device with DRI_PRIME=1 . is there a solution to solve screen tearing and set default DRI_PRIME=1 some where? i hope this is my final Q reg this topic. – bCi Jun 19 '20 at 00:33
  • So ask a new question regarding tearing on dual graphics or find an existing answer. – Pilot6 Jun 19 '20 at 07:06
