I've had the same problem with my laptop. I've found that if I lock Ubuntu (go to the little gear in the upper right corner and select Lock) it won't freeze up and become unresponsive. Not sure why that works but just closing the lid doesn't... I hope that helps some.

two things First, fix grub resolution: sudo nano /etc/default/grub Now, locate the line #GRUB_GFXMODE=640x480 and change it to this: GRUB_GFXMODE=1280x800 GRUB_GFXPAYLOAD_LINUX=keep Set to your screen default instead of 1280x800 (1360x740 for example). Next, add framebuffer: echo "echo FRAMEBUFFER=y" | sudo tee /etc/initramfs-tools/conf.d/...

Finally, I wasn't able to make xcalib work. Instead, I installed CompizConfig Settings Manager as instructed in the solution here and started using the shortcuts in CompizConfig Settings Manager -> Accesibility -> Negative. If you cannot see the Negative option, you have to install compiz-plugins: sudo apt-get install compiz-plugins

I fixed it. Had suspected a brightness problem - as it had happened to me with android. I tried the development chNnel and was able to very dimly see the screen. Turned the brightness up from minimum, and problem solved.ta

How about xset dpms force standby which just does the obvious, turns the display off (there are options of on, off, standby, suspend). You can simply use the reverse xset dpms force on to resume; you could have a script linking via ssh to turn the other PC's display on/off as required: xset dpms force standby; ssh other_pc xset dpms force on

If making the screen sleep works, then almost certainly the toggle- script below will work: #!/bin/bash # --- set your monitor below monitor=VGA-0 # --- if [ -z "$(xrandr | grep $monitor | grep +)" ]; then xrandr --output $monitor --auto else xrandr --output $monitor --off fi The script toggles on/off a monitor, to be set in the head of the script: # ...

It seems common for brightness Fn keys to not work on Asus machines. On my Asus X205TA the brightness function keys don't work natively but I can use xbacklight as a workaround: sudo apt install xbacklight commands: get current brightness: xbacklight -get set brightness to 50% xbacklight -set 50 increase brightness by 10% xbacklight -inc 10 ...

Toggle- dim a specific screen The command to dim the screen (not switch off, but not "sleep" either) would be: xrandr --output $monitor --brightness 0 You can however easily toggle- dim the targeted screen with a keyboard shortcut. Add the script below to a shortcut: #!/bin/bash # --- set your monitor below monitor=VGA-0 # --- if [ -z "$(xrandr --...

I found out there was a bug related to this unexpected behavior. Bug #1292041. This got fixed recently with the release of a Unity patch. See https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1292041 After updating the OS, it now works well on my setup, the monitors blank off, and stay that way until I hit a key or move the mouse.

You should install the proper display drivers. Enter in System Configuration -> Software and updates, in the Additional drivers tab you should see a list with some Intel-GPU drivers (these used to be privatives). Choose the most recent one and apply changes. Restart and you should be able to choose your screen resolution.

To share I use Chromecast plus Chrome Plugin. To split only with HDMI/VGA cable.

I've used HDMI and VGA connections to share my screen. I usually extend rather than share. This only works if your computer is close enough. Relatively long cables are available.

For me (with Lenovo X61s) the unwanted display dimming when unplugging from line power was apparently not related to power management software or similar, but rather due to a BIOS setting for screen brightness in Config-Display. Via that BIOS setting it was possible to avoid the dimming.

Another option is the application Redshift, which in addition to adjusting brightness can also adjust the color temperature to reduce the blue light at night. Example usage: redshift -b 0.8 will set the brightness to 0.8 on a scale of 0 to 1

Moving the mouse to a defined (absolute) position ..is simply done by the command (e.g.): xdotool mousemove 200 200 To move the mouse to the centre of the screen however is a relative command, for which we need to read the screen's information and do some calculations. This is done in the two small scripts below. Straightforward version (move cursor to ...
