Laptop + external monitor issues

Recently I started this thread: xrandr does not detect external monitor native resolution
That issue was resolved after xorg and ATI driver update

But now I have another annoying issue.

If external monitor was connected before turning laptop on - I got black screen on both LVDS and DFP1. Later DFP1 goes to stand by as no signal detected. Neither CTRL+ALT+DEL, nor CTRL+F1, CTRL+ALT+BACKSPACE helps. The only way to reboot is to make hard reset

If I plug in external monitor after booting KDE - no problem. Ok, let’s say we can use it as workaround. If I now disconnect the monitor - desktop is being resized back to LVDS native resolution 1280x800, that’s good, but Desktop area remains 1920x1080! See this screenshot:

This black area is not visible, but mouse cursor goes away the screen edge. If you hit PrintScreen you get 1920x1080 picture instead of expected 1280x800. What is this new cr**? I have never seen this before on 11.3

Oh… this 11.4 has introduced so many bugs and annoyances… I want my 11.3 back… :frowning:

is this a monitor connected by USB?

if not, STOP connecting or disconnecting it while the system is powered
up…unless of course you want to fry the circuit to the graphics
card/chip, the motherboard, or the monitor.

maybe a slower moving operating system like Slackware, Debian, Mac or
ever MS-Windows would fit you better…

it IS available for download and install…
but, you should log your bugs before moving back…otherwise they may
still be alive crawling around in 12.1… if you don’t do it, it can’t
be fixed…

it’s HDMI-D which supports hotplug

I believe this is a kernel issue for some built-in graphic chip sets like those from Intel, one we must live with until it is fixed some time into the future. Attach the external monitor after a reboot is finished. You can then use a Ctrl-Alt-F1 then a Ctrl-Alt-F7 to cause the external monitor to be recognized. It is a pain, but at this point, I am not sure what else one might do except to switch video GPU’s, which is not too likely on a Laptop. I have not had this issue using nVIDIA GPU with the proprietary video driver loaded.

Thank You,

oh, i forgot about those!
(and, sorry i have no idea how to help you with the problem, except to
say: maybe if you write ATI and ask them to provide their Linux driver
to you . . .)

Filed bug: Access Denied

After disconnecting external FULL-HD monitor from laptop Display Setting window
appears that restores native laptop resolution - 1280x800. But desktop size
remains 1920x1080 which results in mouse cursor going of of the screen.

Visible area is 1280x800 but if you do a screenshot you get image 1920x1080
with black areas in the right and bottom (see attachment)

Reproducible: Always

Steps to Reproduce:
0. Set your laptop to native resolution 1280x800

  1. Connect FULL-HD 1920x1080 monitor to laptop over HDMI
  2. Display Settings window pops up
  3. Configure clone mode with new resolution 1920x1080 (laptop remains 1280x800
    but show only left upper part of the desktop which is OK)
  4. Now disconnect external monitor
  5. Again Display Settings window appears with restored resolution 1280x800
  6. Apply new settings, resolution resores and Desktop is fully viewed on laptop
  7. try to move mouse to the right side of the desktop - it is gone. The same
    occurs at the bottom
  8. Make screenshot to verify that your desktop is 1920x1080
    Actual Results:
    Desktop remains 1920x1080 with visible area 1280x800

Expected Results:
Desktop should resize to 1280x800 to be the same size as visible resolution
