I am familiar with startx command, but I need the opposite. E.g., I use Ctrl-Alt-F2 to get to a console and, while in the console I want to restart X. I tried stopx and restartx, but both gave "command not found." Google told me to use /etc/init.d/gdm stop and then start to restart it, but that yielded "no such file or directory."
This is a System76 computer with nVidia GeForce GTX 765M and Haswell core i7-4810MQ. When I installed Xubuntu I just let it install its default driver, which is xserver-xorg-video-nouveau 1:1.0.10-1ubuntu2 (the latest available in the repos). I have not installed bumblebee or anything to take advantage of the advanced capabilities of the GTX 765M and Haswell chip, nor have I ever tried the proprietary driver. I suspect a problem with the nouveau driver but I cannot rule out a hardware fault. The symptoms are thousands of short, thin red lines all over the display, most visible on darker objects. For wallpaper I use a solid white color, and the lines do not appear there at all. The display continues to be usable after the lines appear, although some things are harder to read. The lines appear at random times and once they appear they stay. This first happened late in the afternoon at the July Clinic. Since then they have appeared four more times. In each case the cure is to reboot; logging out and back in again does not solve the problem. Note that the *buntus disable Ctrl-Alt-Backspace. (Why?) There are no hardware related issues that could explain this; e.g., it has happened early in the morning when the house is cool, and it happened a couple of times before the soda in the keyboard incident. And if the hardware was failing because of some condition, why does rebooting the computer always cure the problem immediately? But neither can I come up with a software trigger; in each case I was doing something completely different. I only wanted to try stopping and restarting X, although I suspect it will make no difference, as the lines appear in the console as well. Any other suggestions and observations welcome. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
