I had same problem when I upgrade Xubuntu from 14.04.4 to 16.04.1 . Solution: aptitude versions xserver-xorg-video-intel look lines with "c" begins and install xserver-xorg-video-intel with latest version, for example: aptitude install xserver-xorg-video-intel=2:2.99.917+git20160325-1ubuntu1

A workaround: go to Panel Settings, make the panel smaller (by dragging it) and maximize it again (there is a "maximize panel" button). After that, windows do not go beneath it anymore.

I resolved the issue. Although I attempted a manual uninstall of the manually installed 361 driver, it failed to clean-up all the shared objects and so what I was experiencing was essentially a library problem. After purging all NVIDIA packages using apt, I resolved this as follows: Locate all the 361 driver shared object files using (excludes any trash ...

On http://packages.ubuntu.com/ you can search for packages containing a file. For X11/extensions/Xcomposite.h that finds libxcomposite-dev

I was able to resolve this by manually setting up my own /etc/X11/xorg.conf: Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "...

One suggestion is to try xscreensaver: sudo apt-get install xscreensaver On my own system I have had more reliable power saving / powering down / blanking with this application. A screenshot from my own Xenial system to demonstrate the power management options: And as a bonus there are some truly amazing screensavers...

It turns out that the Kernel upgrade was a red herring -- the issue was the secure boot upgrade that happened at the same time, which blacklisted the NVidia drivers. This is essentially the same issue as found here: Ubuntu 16.04 kernel 4.4.0-21 not loading nvidia/vboxdrv modules anymore (Required key not available) Confirmed by running $ sudo modprobe -v ...

Same problem, here. I booted into 3.13.0-91-generic and everything is fine. However, booting into 3.13.0-92-generic introduces the problem. It appears as if my Nvidia X Server settings have been completely wiped in 3.13.0-92-generic. Edit: Disable secure boot as mentioned in the accepted answer.

Intel still performs better as you can see here: https://www.phoronix.com/scan.php?page=news_item&px=Intel-DDX-May-Tests OTOH, there are a lot of discussion about the slow development in the Intel driver: https://www.reddit.com/r/archlinux/comments/4cojj9/it_is_probably_time_to_ditch_xf86videointel/ To make it complete, the last open source developer ...

Yes, unfortunately click-lock is still not available. All the more frustrating is that an announcement was made, prior to the release of 16.04 LTS, that this feature should be available. Apparently it had been an oversight for all these versions over all these years that this basic, core functionality had been left out. My understanding is that they thought ...

I may have a partial answer for you, if you are using a lenovo X... with touchpoint/touchpad. There is a "known" bug with the synaptics mouse buttons. If you try a USB mouse and have no problem, but with the touchpad/touchpoint mouse (build into the keyboard) you do have random responses that can delete swaths of text as you type, then this may be the bug I'...

This behavior is initiated at login and overrides the command if run at boot. To make this permanent, just add the lines below to the end of the .profile in your Home folder. # Turn off screen blanking xset s off && xset -dpms If you don't see .profile, open your Home folder in your file browser, click on 'View' and select 'Show Hidden Files'. ...

In my case (GeForce 980, running Ubuntu 14.04 LTS), the issue was solved by disabling the Nouveau drivers and using the latest NVIDIA proprietary driver: 1.) Download the NVIDIA driver install script. Since you're stuck in a login loop, you can download the driver on another machine and scp it over to the affected machine. Don't run the script just yet. 2.)...

the EDID data returned by your monitor is not correct. This data is how the monitor communicates its preferred settings to the graphics card. There are several ways to fix this : try a different cable - if you have another one its worth a try , also try your cable on another system. define your monitor settings in your xorg.conf - add a monitor section ...

Three options: Install Xenserver and run Lubuntu and Kubuntu with hardware passthrough to each simultaneously, spinning down one or the other as necessary (I am willing to bet your i3 will actually handle this nicely) Install KDE on Lubuntu and switch DEs at the login screen Install Kubuntu alongside Lubuntu and dual-boot using GRUB to select your OS of ...

There's essentially three ways to do what you want: Set up a dual boot system. This means that Lubuntu and Kubuntu will be completely separate, on two different partitions. However, you can share data between them, e.g. with a shared partition for data, or by directly copying files from one partition to the other. This may use less resources (memory) than ...

Installing ubuntu-desktop is not enough. The problem is that, in this context, the program is run outside of an X server. You could try to declare the DISPLAY variable before calling it, making it use your (newly installed) X server... but you'll probably have permission issues. This would look like: export DISPLAY=:0.0, which is the default (but is not ...

As of Ubuntu 16.04, it seems to be /usr/share/lightdm/lightdm.conf.d/100-custom.conf and it wants to contain: [SeatDefaults] xserver-allow-tcp=true

You might need other x11 dev packages too. libxext-dev, libxpm-dev, libxrandr-dev, libxrender, but maybe not if your compiles were OK. Now the complaint of not finding -lX11 is odd since that should be in in the libx11-dev, but maybe the .so is just a link to the actual library in package libx11-6. In that case, all the other dev packages will need the ...

sudo cp --preserve=timestamps /home/CorrectUser/.config/monitors.xml /var/lib/lightdm/.config/ This fixed my resolution in login screen. When i tried to hardlink instead of copy,it didn't worked.(the hardlinking operation failed)Weird

+1 for all the research effort, however... Hate to break it to you, but the fact is it's working as intended. A splitter is just that - a splitter. Nothing more, nothing less. All it will do for you is duplicate the signal. A quote from the link you provided: The VS92A is a video splitter that not only duplicates the video signal from any VGA, XGA, ...

Could be something to do with proprietary drivers; I encountered a similar problem on 16.04 after choosing to use nVidia's proprietary drivers instead of X.Org Server, couldn't login anymore. If you are using proprietary drivers, consider falling back to X.Org, so far I haven't encountered a better solution. $ sudo apt-get purge nvidia* This should work - ...

Just to update in case useful to anyone else. It turned out it was a hardware fault with the graphics card, so I tried the oven baking method described in the overclockers link and it worked!! Graphics now all A OK. 10mins at gas mark 5 did the trick card ready for baking
