On newmode, 1280x1024_60.00 is enclosed in double quotes, whereas on addmode and output it isn't. Use double quotes on those two commands too. At least, this is the correct syntax. An additional problem is that you are trying to add a mode to a disconnected port "VGA-0 disconnected (normal left inverted right x axis y axis)" which won't work. The port ...

TL;DR Use: xbacklight ddccontrol redshift xgamma Backlight vs pixel values First and most importantly, if at all possible adjust the display backlight, rather than using software correction of pixel values. If you dim the backlight you still get full or near-full dynamic range, giving you a clearer, "deeper" image that tends to be more readable. ...

I have a similar issue after updating 16.04 on a Thinkpad T440. My hdmi display is recognized (right definition and so), works for couple of seconds and is then disconnected. If I wait, ubuntu reconnects to the display, refresh the configuration, and again after few seconds it disconnects from the display. It was working perfectly before the update. uname: ...

The problem in your case is that when you are connecting the external monitor, it is by default being taken as the primary screen which is in left and you have to move your cursor to right of your extended monitor to get it on the laptop screen.

First save any work in case your screen turns off and won't turn on without restarting. What I am going to suggest is temporary to begin with; you can make it permanent if it works. Go to the terminal and run cvt 1920 1080 60. This will output a string of text or two. The last one should start with the word Modeline. Copy from the first text after ...

I also got the same effect after the latest update on Ubuntu 15.10 yesterday. It feels like some weird Compiz plugin has been enabled, but I can see nothing in Compiz. The text is blurry by default, but passing a mouse over it brings it into focus. But not all areas come into focus. Images also seem affected. My computer has Nvidia card, and I updated to the ...

Running the following will do the trick. xrandr --output DVI-0 --brightness 2 or change the brightness value to what you desire. If you want to change the configuration of an output, then you need the name of the output. This name is part of the output of xrandr or use xrandr --current, for example LVDS1. The brightness can be changed like this: ...

From the xrandr output it seems that no resolution is set for the TV. Try to set one of the resolutions listed under HDMI-1 in the xrandr output. For example: xrandr --output HDMI-1 --mode 1360x768

I used arandr to get the right xrandr configuration in the form of a shell script and set it up to run at session startup to make the change permanent. Unfortunately, even though running the script fixed the issue, it would not be automatically done at the beginning of a session, so I have just upgraded to xfce 4.12, which has better support for multiple ...

I had exactly the same problem and here is what worked (well partially) for me: Edited /etc/default/grub as root Changed the line where GRUB_GFXMODE was set. It was earlier having the value 800x600. Changed it to 1366x768 Ran update-grub Rebooted. Still no other resolutions are showing when I go to display properties but at least the default (rather the ...

As far as you speakers go on your laptop, make sure you have not got a hardware mute button that is disabling them. Then check any software mute that is enabled. Finally if all that checks out, check BIOS settings to make sure there are no speaker settings in there somewhere that need to me adjusted. As far as display goes, try another cable - and acreen ...

First thing to try is to drop to a lower resolution and see if the problem goes away. You didn't mention at what resolution Windows is actually running, along with the refresh rate. The dot/pixel clock is generated from other values, see http://arachnoid.com/modelines/ Section "Monitor" # HorizSync source: xconfig, VertRefresh source: xconfig ...

I have exactly the same problem. I have two monitors, one on DVI, one on VGA. Everything worked fine with Kubuntu 15.10. Now, with 16.04, you can see that during the boot up, the VGA monitor stays black, but Ubuntu thinks it activated it. Also for me, the only workaround is to deactivate the second screen in the system settings and to re-activate it. Then, ...

Yes, it is possible to install Ubuntu 16.04 LTS on this system. Canonical has has discontinued support for the proprietary fglrx driver but the existing radeon/amdgpu drivers are sufficient replacement. Note: I had "vanilla" Ubuntu 15.10 installed on this system from USB drive and then upgraded to 16.04 LTS.

I had a problem with setting the resolution higher on my Dell Inspiron 1000 when I was running Lubuntu. My assumption is that by VGA you mean resolution higher than 640x480. The fix I found was to set xforcevesa. Now I have 1024x768, 800x600, and 640x480 on Lubuntu 16.04. If you need help setting xforcevesa see the following. How to set xforcevesa? This ...
