I also see MPlayer artifacts streaming 720p to a Surface Pro 3 with Ubuntu 14.04 installed, but without using vaapi, instead using -lavdopts threads=4 (x86 multithreaded H.264 decode). The artifact is not a "green frame", but looks like it occurs with similar rate and frame position as described. I was able to get improved results by turning off Network ...

If you are using the VGA adapter through a display port the system becomes unable to detect your resolution properly (don't ask me why). Try to use a DVI adapter instead, if possible. Solved my problem when I got stuck with resolution issues.

If you care about having the option to switch between the nVidia and intel chips, try Brian's solution. If you're fine just using the nVidia chip, select the 'discrete graphics' option in your BIOS. I've read somewhere that the VGA port is not wired to the intel chip so you'll have to enable the nVidia chip to use the extra port. I had a problem similar ...

Open Terminal, run sudo gedit /etc/rc.local It will ask for password. Type your password. Then, the text editor will pop up with rc.local file opened. It contains some stuff and in the end exit 0. Before that exit 0 line, add below commands to reduce brightness in Ubuntu: sudo sh -c "echo x > /sys/class/backlight/intel_backlight/brightness" sudo sh -c ...

As long as you have an HDMI or VGA output, yes it'll work fine. You won't get amazing graphics, especially with games, but you'll have another monitor in which to do work.

Try to run applications which use different graphic libraries (GTK, wxWidgets, QT, pure X11) Maybe you will notice that some apps get distorted fonts while other do not, and find out which library should be updated/reinstalled.

Which version of the Graphics Installer are you using? The current one seems to support only Ubuntu 14.10. The Intel Download Page tells you that: Beginning with the v1.0.8 release of the Graphics Installer, we discourage using the Graphics Installer with Ubuntu 14.04. Your error tells you that the installed version of a packet is not the one which the ...

Posting as an answer instead of commenting. I've installed Win7 Pro x64 as I purchased it a while back and the machine didn't detect it, at all. Opened up the laptop, gave it a thorough cleaning and reassembled it, still nothing. Can only believe that the chip died. I remember at some point I was toying with a microcontroller in a cirtuit board of my ...

Getting mad is understandable, but don't get mad at Ubuntu. Wireless devices both internal and external, simply wear out. I don't know if there is a particularly popular chip which is prone to failing or if the problem is caused by overheating. In any case, there is a simply short-term fix, and that is to buy an external usb wifi adapter which is known ...

This being caused by a virus is very unlikely. I have the same problem, also Ubuntu 14.04 on Thinkpad T450s, and the following workaround that someone suggested on Launchpad works for me, although it has a noticeable negative impact on graphics performance: sudo mkdir /etc/X11/xorg.conf.d/ sudo -H gedit /etc/X11/xorg.conf.d/20-intel.conf Add the ...

Finally got it fixed myself. did apt-get dist-upgrade and the graphics errors were fixed. (including WebGL) but the sound glitches are still present. Answering my own question so it might be helpful to someone else having the same problem and no community support. :) Thank you.

I'm sorry to tell you this - but those smudges are a clear sign that your HD3650 is starting to fail. Especially if they become more frequent the longer you use the computer. I had that same issue on the same card on a laptop of mine. Regardless, if you want to exclude a driver problem, you can just download an image of a later (14.10) or earlier (I would ...

I'm out on a limb here, but do you perchance have an X3500 or X4500 Intel card and an odd amount of RAM installed / unequal RAM sticks? Because this is a known issue with those configurations: https://bugs.freedesktop.org/show_bug.cgi?id=28813 It affects Windows systems too, albeit less severely: http://support.lenovo.com/en/documents/ht001223 In ...

I have experienced the same problem with 27" 2560x1440 monitor connected by DVI. The solution was to use cvt -r 2560 1440 reduced blanking option '-r' and not to write desired frame rate.

For one, you must do "make install" to install the compiled drivers. You may also need to set the configure options.
