- I have observed some strange behaviour on my system.
-
- Once in a while, perhaps after a couple of hours of computer use,
- a virtual terminal will go into a "one-line" mode. This has not
- happened frequently enough for me to be certain about exactly when
- it is likely to occur, but for the last couple of times it has been
- in response to my entering a 'less' command like:
- less wx*
- where wx* matches one file.
-
- What happens is that the screen scrolls up, filling blanks from the
- bottom, except for the bottom line. The contents of the file are
- displayed in the bottom line. This leaves all except the bottom line
- blank. The virtual terminal is now in a one-line mode, with everything
- happening in the last line of the screen (although perhaps the blank
- part of the screen is still scrolling, but I can't tell). It remains
- in this mode when I quit less. I have not discovered yet how to get
- the virtual terminal out of this mode. Fortunately, it has no observed
- effects on the other virtual terminals.
- The effect may happen on any virtual terminal.
- Running the identical command from another virtual terminal immediately
- after the problem occurs has not resulted in the same problem on that vt.
-
- Has anyone else observed this?
- Is it a bug in less, or the kernel, or me?
-
- I am using 0.97pl2 and a Hercules card. My less is from the 0.96c
- mcc-interim distribution.
-
- (p.s. I wrote this message via kermit on a VAX editor and every so often
- the screen behaviour gets out of sync with what the VAX thinks it is.
- Typically I will use a cursor key to move up the screen only to find
- that it won't move up but scrolls the bottom part of the screen down
- (starting from the cursor line). I can break out of this mode by
- hitting the HELP key.)
