Created attachment 119034 [details] Xrandr output before setting the dpi manually Hi, My setup is the following: PC: HP T620 Plus with two AMD graphics card Monitors: 3 Dell 4k Monitos running at 1920x1080. Two are attached to the primary card and one to the secondary card. After activating the secondary GPU with "xrandr --setprovideroutputsource" changing any XRandr setting (resolution, rotation, ...) leads in a too small framebuffer. It seems that the dpi is wrongly set. It is also not possible to change the framebuffer with "xrandr --fb". The following commands will fix the problem: ----------------------------------------------------------------------- user> xrandr --dryrun --verbose --fb 4080x1920 screen 0: 4080x1920 0x0 mm infdpi user> xrandr --verbose --fb 4080x1920 screen 0: 4080x1920 0x0 mm infdpi X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 7 (RRSetScreenSize) Value in failed request: 0x0 Serial number of failed request: 52 Current serial number in output stream: 54 user> xrandr --verbose --dpi 96 screen 0: 4080x1920 1079x507 mm 96.00dpi --------------------------------------------------------------------- The following versions were used: Xorg-1.17.2 xf86-video-ati latest git version (ce9914a) mesa-11.0.0 libdrm-2.4.64 libLLVM-3.7 It does not matter if using DRI2 or DRI3. It does not matter if ColorTiling2D is on or off.
