I have a dell Inspiron 15R 5521 with radeon 8730M / intel 4000 dual gpu configuration running Ubuntu 16.04 running kernel 4.8.1.I have been facing horrible screen tearing when using my discrete GPU using the DRI_PRIME=1 command.

I tried the solution given in this link here. However when is create this config file, I get a black screen on bootup or whenever lightDM restarts with the error 

radeon vce init error(-110)

I remove that file the system back to boot without error, however is there any other solution to handle screen tearing while using my radeon gpu?

--EDIT-- i added the output of the file generated by the code

Ubuntu 16.04.1 LTS

as for the xorg.conf it gave the output cat: /etc/X11/xorg.conf : No such file or directory is that normal ?

-----EDIT-2----

So i tried to set up xorg.conf in an attempt to fix the issue using X -configure but i get the following error

Number of created screens does not match number of detected devices.

on googling the issue i found a lot of solutions that applied to different cases like dual monitor setups and all but none that fit my case.

here is the full log file describing my issue. Really appreciate if somebody could help me with this

  • To get back to normal, on boot press shift key, choose recovery, check for free space then drop to shell and remove that file. – user.dz Nov 26 '16 at 22:25
  • already did that . System works as before but the screen tearing stays – B0rn2C0de Nov 26 '16 at 23:51
  • I'm not experienced with this, but adding more info to the question may attract users faced same issue. Could you [edit] the question and add the contents of ~/Desktop/ubuntu-graphic-info.txt generated by sudo sh -c "lsb_release -sd; dmidecode -s system-product-name; echo ==; lshw -c display; echo ==; xrandr --verbose; cat /etx/X11/xorg.conf" | tee ~/Desktop/ubuntu-graphic-info.txt – user.dz Nov 27 '16 at 08:40
  • added the info from the command – B0rn2C0de Nov 27 '16 at 18:34
  • Same case, no solution, no driver support https://askubuntu.com/questions/418454/how-to-install-mars-radeon-hd-8730m-drivers-is-it-supported & this one too from Ubuntu forum https://ubuntuforums.org/showthread.php?t=2234328 – user.dz Dec 05 '16 at 14:05
  • Have you tried the proprietary driver https://support.amd.com/en-us/download/desktop?os=Linux+x86_64 ? I'm not sure about results either. Read how to uninstall it first, at least you can fix system, if it does break the GUI boot. – user.dz Dec 05 '16 at 14:23

    The support for proprietary drivers was drawn in 16.04, They were replaced by these opensource drivers – B0rn2C0de Dec 05 '16 at 15:53
