Re: Frozen mouse and keyboard
Thanks Brad for your contribution. I don't think anything can be done with the keyboard when the freeze occurs.

Re: Frozen mouse and keyboard
Thanks very much, David, for your help. Unfortunately it is not possible to log in to the PC from elsewhere. As to most of your other points, they will have to wait for another similar freeze. I was not able to check logs because, subsequent to the freezing, the PC had to be rebooted due to a mains power cut and the journald system does not persist across boots.

Recently there have been a few occasions when the PC has failed to be woken up in the morning after being left overnight. The mouse and keyboard are frozen. Sometimes the monitor appears to be off and on one occasion it was on. I have had a separate issue which I think might be the monitor power saver communicating with PC. If I turn off the monitor but leave PC on monitor will not wake up when turned back on. disconnecting the power supply to the monitor and plugging back in resolves that. It used to be that the monitor would not turn back on after going in standby mode so I have deselected all power savers in monitor menu. so rather than hard setting the PC, try power cycle the monitor mick

Apart from that, I would take a careful look at the BIOS settings under Power Management. Assuming your mouse and keyboard are USB or unwired, perhaps the USB ports are powering down too? If you plug in a USB stick, does it light up as normal? If there's an ethernet card, is the light still on? Does it react to (un)plugging? Disks spinning?

Modern filesystems/journals etc are pretty forgiving. Modern hardware should be unharmed by the experience. (Unlike back in the days of parking disk heads.) Cheers, David.

It is randomly, but it looks like it has something to do with either firefox or the graphics driver. IMO it looks like X (or something related to the graphics card or X), is hanging.

When lucky, you can see the mouse cursor move, but clicking is not possible any more. It also appeears, that if you wait, it might happen, the system is starting to run agian (after several minutes), but this is not guaranteed.

The usual recommendation for a first test is to see whether there is any network activity e.g. response to ping or ssh. Also try Ctrl-Alt-F3 to see if a console is reachable as X might have problems. Have you checked logs to see whether there is anything suspicious before the freeze? If there isn't, the odds are in favour of a hardware failure. If that looks to be the case, I'd open up the machine (assuming it's not under warranty, if it is, it's someone else's problem) and reseat all the movable connectors and RAM. There's less chance of contact problems with SATA than with the big old PATA connectors, but it's not impossible.

I have an intermittent problem that might or might not be relevant. I have two computers that I use as almost daily drivers, one running Wheezy (I know) and one running Jessie (yes, I know). They are connected to one set of keyboard / mouse / monitor (by a KVM, but I am sure that the KVM is not the source of the problem I'm going to describe). If if leave the computers for some period of time, of course the power saver mode turns the monitor off (or to standby or whatever -- the point is it is dark). If the KVM is set so the Wheezy computer is using the K/V/M (keyboard / video / mouse, I guess), I never have any problem if the monitor has been powered off -- if I press a key on the keyboard or move the mouse, the monitor (in particular -- keep reading) wakes up and I'm back in business. If the KVM is set so the Jessie computer is using the K/V/M, occasionally (and more often if I leave it that way overnight), the monitor will not wake up (and thus, it appears that the keyboard and mouse are not responsive -- the system appears dead). The way I've found to get around the problem is to actually depower and then repower the monitor -- initially I did that by unplugging it from the wall -- since then I added a "line switch" in the power cord. I leave the monitor unpowered long enough so the red "pilot light" on the monitor fades to black. After the monitor is repowered, the keyboard mouse and monitor work as normal. I can't recall, but I don't think even swtiching the KVM to the Wheezy computer solves the problem -- the monitor seems to get into some strange state. I should point out two more things: * The "monitor" I use is a actually a 32" (modern) TV (that is one of LED, LCD, or whatever the various acronyms are for TV screeen technology) -- it is 1080P resolution, so adequate for my needs (2560 x 1080 pixels, iirc?? no, I don't think thats right -- 1080 vertical, not sure of horizontal) * The first time I had the problem I thought the monitor (TV) was dead and replaced it with a spare. Some time after that (don't recall how long) the same thing happened with the new monitor, and I sort of accidentally found out that depowering and repowering solved the problem. (Fortunately, I did not discard the first monitor which I now assume is good -- haven't tried to test it (I put it in the box for the spare monitor). -- A picture, sketch, diagram, or chart is worth a thousand words -- divide by 10 for each minute of video (or audio) -- instead: create a transcript and edit it to 10% of the original!

Frozen mouse and keyboard
I have a fairly new desktop PC running Debian 11. Recently there have been a few occasions when the PC has failed to be woken up in the morning after being left overnight. The mouse and keyboard are frozen. Sometimes the monitor appears to be off and on one occasion it was on. A hard reboot has been used to reset the PC, but it is not a good idea to keep doing that. There is also a worry that if there is a hardware fault, the situation might get worse over time. Has anyone any idea as to what may be causing the problem and what would be the best way to try and solve it ?

On bootup of newly installed 2.4 Woody, both mouse and

installation, I am able to apt-get install emacs20 and

with the rescue disk, since the machine goes right to
a display manager and keyboard and mouse freeze again.
At the "boot:" prompt, you can enter something like "linux single" and
avoid going into the display manager. Then you can edit the display
manager's startup script ("/etc/init.d/kdm"?) and add the single line
"exit 0" as the first executable line. Now you can restart normally
without the display manager starting (remove the line later when you
want to restore kdm).
What's wrong? And many thanks!
After doing the above, does the keyboard work in console? Mouse
(assuming you have gpm installed)? If you start X with "startx", what
happens? When the keyboard freezes, does the numlock/capslock toggle the
indicator lights?
If the keyboard/mouse works in console, but not in X, you might try
running "dpkg-reconfigure xserver-common" and/or "dpkg-reconfigure
xserver-xfree86" and select different settings.
