When I returned, my monitor was dark. Usually this simply means
that the screen-saver is working. However, I was entirely unable
to recover the display! Although we have been having "electrical
storms" in the past few days, there was no such problem in the
area, and no other evidence of a power outage anywhere in the
house. In a few moments, seeing few alternatives, I powered the
entire computer down brutally, and then rebooted. When I opened
the file that I had been editing in Kate, several VERY extensive
pages of physical printed matter (that I had previously entered --
and then saved, incrementally, several times) were no longer to be
seen -- either via Konquorer or via Kate!!!
Can anyone give me detailed directions for recovering a
more-complete version of my HTML file under these peculiar
circumstances?
Kate usually creates a backup file in the same locations, same name
with ~ added at the end.
If the unclean shutdown caused filesystem corruption you might have
something in the filesystem's lost&found folder (if it has one).
General advice: if you get into such a situation, the "Sys-Request"
keys might still be working.
Alt+SysReq+S syncs the filesystem (writes all pending buffers to
disc)
Alt+SysReg+U remounts all filesystems as read-only (saving them from
being corrupted by anthing to come)
Alt+SysReq+B reboots the system.
I am not sure though if all distributors enable SysRe keys, I just
know I use them now and then (Debian unstable here).
I was not previously aware of Alt+SysReq+x key-chords -- let alone any
of the details. THANK YOU for this information. Right here in
openSUSE KMail (exactly as mis-installed on THIS box!) they seem to do
nothing. The next time I go into Jaunty -- and before I do anything
else -- I will check out these options. Perhaps some useful
information will be developed. As noted in replies to other people, I
AM concerned about NOT corrupting things anymore than I have already
unwittingly done so, so it may be a moment or two! I will definitely
keep you posted on results. THANKS again!!!
I could hardly agree more!
=====
Slightly off-topic for this list is another issue that someone
might be able and willing to clarify for me. Whenever I shut-down
Jaunty ("gracefully"!), I am given a 30-second warning. I usually
click on it. Then a message is displayed to the effect that KMail
needs the password for KWallet. If this were when I am
starting-up, this would be expected -- but it happens during
SHUT-DOWN!!!
Strange, maybe really bad timing (wallet already closed for shutdown,
KMail trying to access an account).
I generally do just that myself -- for essentially the same reasons!
One person suggested
that I delete KWallet, and I like the idea of doing so. But I do
not yet see HOW to do so. Can someone instruct me in this rather
basic task?
I'd rather recommend quitting apps with important data before logout
:) I do that to make sure they really had enough time to write all
cached data back to disk properly.
There was a cerain perverted logic to what I did, and it hinged on my
assumption that doing a lot of careful "Save" operations would give me
the backup I needed. I even saw the file-sizes (current file and
backup file) changing. But it was NOT enough!
Cheers,
Kevin
