Comment 3 for bug 1743797

I installed 'linux-generic-hwe-16.04', as suggested, but there's no change. Perhaps because the radeon.modeset=0 is still in my system - but I can't find where. My boot sequence no longer shows radeon.modeset=0, but it came up when I ran dmesg | egrep | 'drm|radeon'. I've included both outputs below.

I checked all versions of the boot sequence, including the 4.4.0-104 versions, specified in the dmesg output. The recovery mode has 'nomodeset', but no radeon.modeset=0.  I included outputs of the 4.4.0-104 generic and recovery boot sequences below, in case they'd be of use.

Can you tell me how to get at the radeon.modeset=0 settings to remove them, or if you think that's not the problem, offer any other suggestions? My knowledge of Linux is miniscule.

Thanks.
