As per this answer, after setting CTRL+ ALT+ Backspace to gsettings get -sources xkb-options, with the Brave browser open it just pulls down or up the menu toolbar, while with other applications it does nothing. On Ubuntu 17.10 with GNOME, ALT+ F4 is the default to close a window. Wait a second between each press, because each letter is a different kernel action leading to a "graceful" reset. This one is a bit hard to remember, but it involves pressing and holding Alt+ SysRq (system request, often same key as PrtScr print screen) and then while holding those two keys press one at a time in order R, E, I, S, U, B (a mnemonic is Reboot Even If System Utterly Broken, but may also be easily remembered as "BUSIER" backwards). not pressing and holding the power button). If even that doesn't work, the last thing you can do is ensuring a sane shutdown (i.e. If you have done that and your system later hangs, you can press Ctrl+ Alt+ Backspace, which will effectively bring you back to the login screen. One of the options is Key sequence to kill the X server, you can click that run gsettings get -sources xkb-options for recent versions of Ubuntu (according to this answer). The first has to be enabled in advance when your system doesn't hang yet (you could do it right now): open Keyboard Layout settings (I believe this is merged into Keyboard in Ubuntu 12.04), then click Options.

Yes, from inside your chroot(s) you can use the command-line along with croutoncycle to switch to CrOS and/or other chroots.System Monitor shows you an overview of running applications (under the Processes tab) and allows you to end them by right-clicking on the name and selecting the respective context menu item. It's possible that Ubuntu, crouton, and CrOS all updated in that time, that's why it's a good idea to do a crouton update to help keep everything in sync.Īre there any other ways to switch between operating systems other than a keyboard shortcut? If you installed the 'xiwi' xmethod along with the 'crouton integration' extension then you should also be able to switch into your chroot by using the extensions's drop-down menu on the address bar, see below -ĭid ubuntu or crouton uninstall or need an update after a few weeks of non-use?

Up until recently this function, changing OS systems, did work without problems.Īdditional information: If I start a Linux KDE session in Crouton and don't do anything (for example, start an app, such as notebook or something) I AM able to use the Alt-CTRL-Shift-> function to switch back to Chrome.
