.TH UNSTICKPIXELS 1 UNSTICKPIXELS .SH NAME unstickpixels \- Screen loop to try to unstick stuck dots .SH SYNOPSIS .B unstickpixels .RI [ OPTION ]...\ [\fB--\fP] .RI [ INTERVAL ] .SH DESCRIPTION .B unstickpixels shall cycle the colours on the screen between sRGB(100 %, 0, 0), sRGB(0, 100 %, 0), and sRGB(0, 0, 100 %), as fast as possible, or sleep INTERVAL milliseconds between each switch. .PP You should disable powersaving on your monitors and disable the screensaver whilst running this program, or otherwise make sure that screen loop is always displayed. .PP Running this program for a number of hours, especially if combined with massaging defective dots, may heal defective dots. Dead dots (always black) are hard to revive, but stuck dots are more probable to get fixed. .PP You must not run this program if you are epileptic. Seek someone else how can do it for you. .PP .B unstickpixels uses the graphics cards' colour lookup tables to switch the colour displayed on the screen. If your computers does not supports this, the option .B -v may help, it will use the framebuffer indirectly, via the terminal. Unless .B -v is used, .B unstickpixels runs both in .B X and on the Linux VT. .SH OPTIONS .TP .BR \-v Use the Linux VT instead of the graphics cards' colour lookup tables (CLUT). This requires that the program runs under the Linux VT, otherwise known as the TTY. This may not work too great one all graphics cards, some very expensive graphics cards are really bad. NVIDIA is known case of this, why the CLUT utilisation was added. If you are using a graphical environment and do not know how to access the Linux VT, here is how you do it: press .BR Ctrl+Alt+F1 , if this does not open non-graphical login screen, press .B Alt+Right until you get one. To get back to graphical environment, hold down .B Alt+Right until it appears. Whilst unstickpixels may run on most systems (although Mir and, by Wayland's design, Wayland are not supported) this option is only known to function on Linux. .SH RATIONALE Acer/Packard Bell is not willing to repair all defects on my computer, but at least I can run this for several hours and try to revive dead pixels. Playing back a video that is already available on the Internet has some deficiencies: .TP * Requires a graphics card and video player that can play back the video in full screen mode efficiently. .TP * Requires .B X or a video player than can play video outside .B X efficiently. .TP * Requires the video to be downloaded if it was uploaded on Youtube, because Youtube does not properly support full screen. .TP * One video playback is required per defective monitor. .SH "SEE ALSO" No similar or otherwise related programs known, please file a bug if you know any. .TP There are some similar works in form of videos available on the Internet. .PP Full documentation available locally via: info \(aq(unstickpixels)\(aq .SH LICENSE Copyright \(co 2013, 2015 Mattias Andrée .br License GPLv3+: GNU GPL version 3 or later . .br This is free software: you are free to change and redistribute it. .br There is NO WARRANTY, to the extent permitted by law. .SH .PP Copying and distribution of this manual, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved.
