Even if one application or a poor video driver does, you can simply restart the GUI and just keep going on and on. Ubuntu doesn’t tend to leak memory over time. If tests fail, try installing a RAM with greater capacity. Try Memtest86+ to check for fault due to low memory. If you’re getting a lot of freezes, there might be something wrong with your hardware. If you want to do a clean system reboot, execute the following from your terminal( ctrl+ alt+ T) or your console ( ctrl+ alt+ F1) : It works immediately! You can test it by pressing Alt+ SysReq+ F. Sudo nano /etc/sysctl.d/nfĮcho 244 | sudo tee /proc/sys/kernel/sysrq You can change it to 1 or, that which is potentially less harmful, 244. Ubuntu ships with sysrq default setting 176 (128+32+16), which allows to run only SUB part of REISUB combination. Note: You should explicitly enable these key combinations. If you want to kill all processes for one console, you can issue Alt+ SysReq+ K. Kernel will kill the most «expensive» process each time.
If SysReq key works, you can kill processes one-by-one using Alt+ SysReq+ F. There exists less radical way than rebooting the whole system. Or mnemonically – Reboot Even If System Utterly Broken.
REISUB is BUSIER backwards, as in “The System is busier than it should be “, if you need to remember it.
I – Send Kill signal to all processes except for init. E – Send Terminate signal to all processes except for init. While holding Alt and the SysReq (Print Screen) keys, type REISUB. Ubuntu freezes: When everything, keys, mouse. Once you execute, it should bring down the GUI, which will then attempt to respawn, bringing you back to the login screen.ģ. If you’re using another display manager, replace lightdm/gdm/kdm with its name. For Kubuntu, (default display manager is kdm) For Ubuntu 11.04 or earlier (as gdm used to be the default display manager): For Ubuntu 12.04 to 20.04 and above (lightdm is the default display manager) From there you can troubleshoot things or kill offending processes as described in the previous step. If the keyboard is still functional, press Alt+ F2 and run gnome-terminal or try ctrl+ alt+ T (or, if these fail to launch, press Alt+ Ctrl+ F1 to switch to console and login with your username and password). You should then be able to re-login with your usual display manager. This kills all the processes and logs you out. If your GUI is working, then you can simply logout and re-login, but if your desktop/navbar is also frozen, then launch your terminal and execute the following – Sometimes, you don’t know which program is causing a lag or a slowdown, in this case you can certainly restart your computer, but a better way is to simply kill all the processes and relogin. In some special cases the killed process maybe listed by ps or top as a zombie entry only because it’s needed later. It always works provided you have the permission to kill. Note that force killing the process provides the kernel no opportunity to cleanup. If all this fails, as a last resort, you can force-kill by sending SIGKILL (9) as follows:. It sends the default signal SIGTERM (15). To get the Process ID ( PID), you can use ps or top aux in the terminal or graphically by launching the System Monitor. If that doesn’t work, find the name and process ID of your program and kill the process. To kill a program by its name, use killall xyz where “xyz” is the name of the program. You can usually halt a program running in the terminal with Ctrl+ C. Here is in-depth tutorial to see this is detail. Right clicking will cancel and return your mouse to normal. Hover over the offending window and left-click to kill it. #Reset phpstorm ubuntu windows#
In such cases, you can hit Alt+ F2 (or the windows key) and run xkill. Sometimes this does not work as expected. Usually a single unresponsive program can be terminated simply by clicking the X-shaped close button at the top left of the window which would generally result in a dialog box saying that the program is not responding (but you already knew that) and presenting you with the option to kill the program or to continue to wait for it to respond. What could you do to debug and regain control before you decide to pull the plug and restart all over? Does a magic combination like Ctrl + Alt + Delete exist for Ubtuntu? Lets find out… 1. It so happens that when Ubuntu Freezes, all you’re left with is a blank screen or a non-working mouse/keyboard or perhaps you have a particular program that has crashed/frozen. All operating systems freeze sometimes, and Ubuntu is no exception.
