I'm having some issues getting this to work. I'm using an HP Chromebook 14, with Crouton (Ubuntu 12.04.4) installed. I installed the Qt5.2.1 binaries from issue #8, set up my $PATH, and make && sudo make install from the konsole-qml-plugin directory, which went well and without any errors.

When I try to run it (from within GNOME 3), I get errors about a shader failing to compile, and the screen is unreadable (no matter which settings I use). I don't know enough about shaders yet to know why this error is happening, but I could look into it. I just figured I'd ask to make sure I'm not doing something stupid.

Thanks for the help and for writing this! I've been looking for a program like this for years.

Here's what the screen looks like:

And here's the log from running it:

Thank you for your feedback... There was a problem with that shader; some GPUs tolerate those casts and some don't. Please pull the last version and let me know if everything is working now...

Thank you! That fixed it, so now the screen is readable, and I don't get any errors any more (except the overlay one, but that's not the program's fault).
