I am trying to set up two external display monitors in addition to the in-built display. I first used a VGA splitter and connected both the monitors but they came up as mirrors of each other, which is not what I want - I want three distinct screens. I then used one with the VGA port and the other with the HDMI port (using a connector), but now strangley neither gets detected when I go to SETTINGS > DISPLAYS. I can use both of them individually, and in either of the two sockets (HDMI/VGA), so I know its not a hardware issue as such. According to this resource: https://www.notebookcheck.net/AMD-Radeon-R5-Beema.122502.0.html the system graphics should support two external displays.

The output of xrandr when only the portrait monitor is connected is:

Screen 0: minimum 320 x 200, current 2446 x 1920, maximum 8192 x 8192
XWAYLAND0 connected 1366x768+1080+0 (normal left inverted right x axis y axis) 310mm x 170mm
   1366x768      59.98*+
XWAYLAND1 connected 1080x1920+0+0 (normal left inverted right x axis y axis) 480mm x 270mm
   1080x1920     59.96*+

The output of xrandr when only the landscape monitor is connected is:

Screen 0: minimum 320 x 200, current 2732 x 768, maximum 8192 x 8192
XWAYLAND0 connected 1366x768+0+0 (normal left inverted right x axis y axis) 310mm x 170mm
   1366x768      59.98*+
XWAYLAND2 connected 1366x768+1366+0 (normal left inverted right x axis y axis) 410mm x 230mm
   1366x768      59.62*+

And the ouput of xrandr when no monitor is connected is:

Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
XWAYLAND0 connected 1366x768+0+0 (normal left inverted right x axis y axis) 310mm x 170mm
   1366x768      59.98*+

Any help in figuring this out will be much appreciated... Thanks.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
