Follow a chap’s blog, but watching him wave his arms around as he expounds of the world’s problems gets a bit tedious so I watch one of a number of live webcam collations in a new tab over it. Just occasionally, after a variable time, this livecam page will lock up - just stop and if, as some do, the stream includes a local time ticker this will freeze. The underlying tab talking at me continues so I’d guess the problem is limited to the one tab, but as I’m full screen I can’t close it or access the panel to close Brave, and Mint doesn’t appear to have an equivalent of Windows’ ctl-alt-del combination so I have to kill the entire operating system via the power button and reboot.
2-part answer - and the first part is much more relevant to linux than to Brave:
Mint doesn’t appear to have an equivalent of Windows’ ctl-alt-del
In many linux versions Alt+F2 will open a “Run Command” dialog on the screen. Type xkill in the dialog and press Enter. Your cursor should change to an X. Click a window and the xkill utility should determine what process is associated with that window and attempt to kill that process. The window should close. Or - keying in reboot or poweroff in the xkill dialog and pressing Enter should produce those results.
Second part of the answer: How long your computer takes to respond to Alt+F2 and to any subsequent commands depends on many things such as resources (e.g. processor, memory, etc.) and how those resources are deployed - in addition to the Brave instance. Though some linux installations require fewer resources, that doesn’t reduce the requirements of installed applications, e.g. Brave.
