I found out why the screen turns black when I login on my personal account. It appears I have accidentally pushed a button that toggles between monitors/beamers when connected. When nothing is connected to the laptop the build-in screen still turns off. This is done by pressing Fn+F8. This is applicable for the Asus R500V series My thanks to the people who ...

[If this doesn't work, I'll remove it] If it does, then it'll be a dupe FYI. At GRUB boot to recovery mode and drop to a root shell. 1) Mount the file system as R/W: mount -o remount,rw / 2) Next, run sudo nano /etc/default/grub 3) Then add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" Becomes: ...

Using sudo apt-get install xserver-xorg-video-intel fixed the issue for me. However, now the mouse cursor disappears when waking from sleep. I haven't found a fix for this, but a work-around is to use Ctrl+Alt+F1 and then Ctrl+Alt+F7.

No. Note that as of date of last testing (2014, xcalib version 0.8) xcalib has not been able to invert the colors on all monitors in a multi-monitor setup, because all monitors are presented by the X11 server as a single screen. Thus this limitation is coming from the X11 server. xrandr-invert-colors does not have this limitation, because it ...

Preparation: If you haven't done so already, install the Terminal app. In the Terminal write: $ dconf write /com/ubuntu/touch/system/dim-timeout "@u 0" The dim-timeout Key wants an unsigned int as a value. That's what the @u is for. The number stands for the seconds after the screen is dimmed (0 = infinite). (Since the setting is stored for the local ...

I looked on help.ubuntu.com and found this (again, it was someone wanting to disable the dimming): Terminal command for checking/unchecking "Dim screen to save power"? So I tried: gsettings get org.gnome.settings-daemon.plugins.power idle-brightness Got back 30. So, I tried this: gsettings set org.gnome.settings-daemon.plugins.power idle-...

which graphics drivers are loaded? Can you show the output of dmesg? I believe that your R9 is using open source amdgpu driver. In my laptop (R6 APU + R7 GPU) I also have many issues related with the amdgpu driver and kernel 4.4 combination. In my case I found several issues in dmesg related to amdgpu and R7 card. If you could take the risk try the following:...

The most likely problem here is that your mouse is broken. Try unplugging your mouse, and see if the problem goes away. If it does, then it's an issue with the mouse itself, not with Ubuntu. The most likely problem is that there's some dirt or something similar in the mouse, which is confusing the sensors. If it is the mouse itself, you could either get a ...

I'm just a novice Ubuntu user, but I've noticed there seem to be a lot of settings to toggle in the Compiz Config Settings Manager application. There might be a section in there for monitors, screen saver behavior or power management? If you don't have it already, you can download it from Ubuntu Software. Just be careful with what you change!

I had faced the same issue in my xps but none of these works. So for a work around I created another user with root privilege and now I can log in with that user account and access all my application and files.

I figured out the problem. The screen sessions aren't "disappearing", they're just detaching. The way I fixed this was by using "screen -ls", finding the PID of the screen I wanted, then using "screen -r " to reattach the screen and allow access to it. Thank you to MadMike for the link.

After confirming in the comments that the pm-suspend command works properly with your laptop, we can now tell it to use that command exclusively to suspend it. Open a terminal and type in gksudo gedit /etc/default/acpi-support Enter your admin password when prompted. Look for the line that says SUSPEND_METHODS="dbus-pm dbus-hal pm-utils" Change the line ...

You can do this with xpra: xpra start :100 --start-child=PROGRAM --bind-tcp=0.0.0.0:10000 xpra attach localhost:10000 As a bonus, it also works remotely – you can attach this window to X (or even Windows!) on a different machine. xpra is like the console programs screen or tmux for X11.
