For the first time ever I have had my Puppy Linux system hang up.
I was browsing using a frugal install of Lighthouse Puppy (32 bit) on an NTFS partition. When I made to display a video full screen the machine hung. Nothing happened whatever keys I pressed. I tried CTRL-ALT-DEL, CTRL-ALT-TAB, CTRL-C. Nothing happened. In the end I hit the power off button. When I rebooted Puppy did not recognise the partition. Windows said it was corrupt. On the second boot of Windows CHKDSK kicked in and resolved the corruption and stored some files in a folder which I could not access! That's a Windows problem which I do not want to discuss here.
My question is simple. What are the Linux keyboard commands I should try to recover from a hung PC before I take the drastic step of hitting the power button?
Thanks for any advice.
Three Fingered Salute for Puppy Linux
Yeah, Magic_SysRq would be the best, but only if a kernel is compiled with this option.rokytnji wrote:1. Hold down the Alt and SysRq (Print Screen) keys.
2. While holding those down, type the following in order. Nothing will appear to happen until the last letter is pressed: REISUB
Did you try that?
Unfortunately, I have not seen a single Puppy with this useful feature enabled!
Just checked and Lighthouse64-602 is not an exception:
Code: Select all
# grep -i 'sysrq' .config
# CONFIG_MAGIC_SYSRQ is not set

Sometimes when my puppy install hangs I press Ctrl-Alt-Backspace and I go to prompt. Then:ICPUG wrote: My question is simple. What are the Linux keyboard commands I should try to recover from a hung PC before I take the drastic step of hitting the power button?

permission denied in Puppy? My version in Windows 7
Great. I was brought back here. Here is what I did to kick me out while replying.
1. Cntrl+Alt+F1
then in there
2. Ctrl+Alt+Del
to reboot. I opened Firefox and my typed reply was sitting there when I hit the restore button when firefox opened.
Worked in Slack0 5.7 install .exe inside of Windows 7.

hmm on another system I seem to have a kernel that kills an app if it threatening to fill the ram to the point of lockup...seems like that would be a good feature to enable for a run in ram distro.
I know nothing about it apart from it works
