Database can be ignored for ddccontrol. sudo ddccontrol -r 0x60 -w 0 dev:/dev/i2c-0 Try with -w parameter values from 0 to 4 and for all available /dev/i2c-* devices. Thanks ddcutil, was not aware of that. Will try and see if it works better than ddccontrol. Rokas Kupstys On 2017-03-20

Re: [vfio-users] Looking for recommendations for screen-switching

You might try installing ddccontrol and trying. Maybe they simply did not bother enough to list it in docs. Maybe monitor is based on same hardware as other more high-end monitors are and functionality is in there even if vendor does not say its supported. Rokas Kupstys On 19/03/17 21:29

Re: [vfio-users] Looking for recommendations for screen-switching

Check monitor documentation. i2c is a protocol for software to control monitor in this case. Monitors usually support it but might not work on all input ports. On March 19, 2017 19:50:38 "Patrick O'Callaghan" wrote: On 19 March 2017 at 16:49, Rokas Kupstys

Run "virsh capabilities" and look for tag. It lists core siblings. Its what you are looking for right? For me this script also is little inconclusive, however seems like libvirt lists siblings right as i cant pin one core to two physical cores that are not siblings. On 2016.03.04 16:34, Jeff wrot
