Please go to your display setting and make sure you have the correct refresh rate set (normaly 60hz or more). The most common cause of screen flicker is low refresh rate

You can download and read the installation instructions/details for Intel's graphics drivers (for Ubuntu 12.04) from here. The direct download link is here. Be careful when installing, track the changes you make during installation (because any changes in packages may cause problems for your U12.04). The reason why Intel's graphics drivers installer is ...

Go to the Power Plan (The battery or Charge icon in the task bar). Change it from Power saver to Balanced or High Performance. Then run VLC again at 1080, see the magic :)

I had this problem and when I finally managed to get to desktop I run Synaptic Package Manager (the old abandoned friend:-)), selected "Origin" from filters, clicked the intel repo (download. 01.org) and then forced every package from the list to downgrade to trusty version. Rebooted, disabled the repo altogether and voila - all reverted back to not-crappy ...

You have started the Intel driver package update, but did not read the full set of instructions! On the 01.org website where you found the link for the PPA, there are also specific instructions for Ubuntu to add the public key to your system so that you can verify downloads from that PPA. You will need to open a terminal window ctrl+alt+t Enter the ...

Use gdebi to install the intel-linux-graphics-installer and you won't have the GPG problems. It should automatically install with the deb package. Use the following commands to do so: sudo apt-get update && sudo apt-get install gdebi cd && wget ...

Downgrading should work. Check the "history" tab in the software center and downgrade all the intel changes from 1.0.5 -> 1.0.6. As far as I can tell, there are two possible causes: The intel update installs a package called i915-3.15-3.13-dkms, which I guess is a backport of the Intel graphics kernel module in 3.15 to the ubuntu 3.13 kernel. This might ...

Okay, if you haven't already tried these, check it out xrandr --output HDMI-1 --set underscan on xrandr --output HDMI-1 --set "underscan hborder" 40 --set "underscan vborder" 25 Another one I came across was this: xrandr --output HDMI1 --transform 1.05,0,-35,0,1.05,-19,0,0,1

Are you absolutely certain there is no option on the TV? I too have Intel HD Graphics and had the same problem, until I changed "Theater Settings" from "Full" to "Native". On my TV this was at the bottom of the picture menu. Other TVs sometimes label it as "Widescreen Settings" or similar.

The problem is that your connection to the external monitors is through a DisplayPort connection to the docking device. The dock is using a single DisplayPort connection to provide both monitors over a single channel. To do this, it is using Multi-Stream Transport (MST), which is not yet well supported in Linux and Xorg. Until the Hardware Enablement Stack ...

I have experienced the same problem. After installing ver. 1.0.6 (on a one month old fresh installation of Ubuntu 14.04) the drivers were damaged and now the only GUI i can get is the splash screen, and if i'm lucky i can get a terminal (requires a few restarts). I have tried to revery to the old xorg.conf, thinking those settings might work, but nada. As ...

Ian's right. Though you might be able to improve overall performance by making sure you have the latest drivers for your card. Head here and download the Intel Graphics Installer for 14.04 64bit. It'll check your system and install any relevant updates.

Quality and detail settings are actually set per-game within the game's own configuration screens. If you open up a specific game and click on "Settings", most games have a "Quality" or "Video" options screen where you can change the quality and resolution settings.

I was using intel-graphics-driver until 1.0.5 with no problem. I have updated to 1.0.6 and I started to have problems. No image at all. I see now that this drivers are not compatible with low latency kernel (funny it worked before) Uninstalled drivers and now I don't know how to fix it. Running on failsafe mode now. I have found a solution. Even if it is ...

I'm inferring a laptop's "Optimus" setup from your question. If you don't need it, using the Intel card alone is probably more power efficient but that relies on the discrete graphics card dropping into lower power levels, controlling fans accurately, etc. I would suspect that for it to work as designed, you'll still need the proprietary driver installed. ...
