[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Chris Jones]

fwiw, you can make screen send scrollback to the terminal with this in
screenrc:

termcapinfo xterm ti@:te@

but I can reproduce the particular issue I mentioned with a fresh user
(which presumably doesn't have that option since it's not enabled in
/etc/screenrc).

[Micah Cowan]

Well, changing the TERM environment variable doesn't trick bash into
sending that sequence. Perhaps bash won't request it, but will interpret
them if they are sent unbidden.

Aha! If I run "screen cat", and scroll the mouse wheel, I get data. It's
definitely looking like screen automatically requests mouse input, then,
which it should not do. As I said previously, this is happening for me
in Feisty (screen-4.0.3-0.2ubuntu2).

I'm reassigning this to screen, as that appears to be the culprit.

Hm, I just noticed that Matthias never mentioned screen, however.
Matthias, was screen involved when you experienced this bug? Otherwise,
the issue Chris and I have just been discussing would be a separate
issue (though, I suspect some program would still have had to invoke
mouse reporting to produce your issue).

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Micah Cowan]

For me, this happens in Feisty as well, though I suspect it depends on
the version of screen running (potentially, remotely)--or possibly bash
--rather than of gnome-terminal.

In order for such a thing to occur, bash must request screen to send it
mouse button events, and screen must in turn request it of the
"xterm"-like terminal running it. It seems likely that, for whatever
reason, bash does not enable mouse-button support when running directly
in gnome-terminal, but does when being run under screen. While it's hard
to say for certain, my strong suspicion is that this is a bash issue,
rather than a vte issue. However, as to whether this is truly a "bug",
I'm not sure.

Note that, scrolling through the scrollback buffer when screen is active
is useless anyway, since screen does not cause anything to be scrolled
in the terminal; rather, it saves things to its own scrollback buffer,
which can be accessed in "copy mode" (C-A C-[).

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Chris Jones]

I have just upgraded my laptop (Thinkpad X40) to gutsy in the last few
days and encountered this.

If I launch a regular gnome terminal and generate a lot of output (e.g.
ls -la /etc/) and scroll with the mousewheel it moves back and forth
through the history correctly.

If I then run screen inside the terminal and generate a lot of output,
instead of behaving as above, the scrollwheel just does the equivalent
of pressing up and down cursor keys - ie yes, it scrolls the command
history.

I am able to reproduce this with an entirely new user with no bash,
screen or gnome-terminal configuration. I am also able to reproduce it
with a python script which uses vte. FWIW, I scroll using the middle
mouse button and EmulateWheel (xorg.conf option). For me this is a
regression from Feisty.

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[PETERV]

I added termcapinfo xterm ti@:te@ to my .screenrc, and now I can scroll in my 
screen windows.  I love it.  Thank you.  I do have one question though.  If I 
use the mouse wheel, or the up & down arrows of the scrollbar, the window 
scrolls, but snaps back to the bottom by itself.  If I want to stay where I 
scrolled to I have to keep my mouse on the scrollbar slider and hold it in 
place.  Makes it kind of difficult to do a cut & paste.  Is there any fix for 
this?  Also, I know this is off topic, but is there any way to get syntax 
coloring in vim when you're using screen?  It works find outside of screen.
Thanks again

It's almost certainly caused by screen -- the mentioned termcapinfo line
(also a variant is commented out in screenrc) "fixes" the problem. Maybe
we should consider shipping that by default :)

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Heath Caldwell]

The problem is with vte (the terminal widget that gnome-terminal uses).
A feature was added that sends a number of up/down keystrokes instead of
regular scrolling if it is using the alternate screen or scrolling is
restricted (one or both of which are the case when using ncurses
applications).

I wrote a patch for vte to make the feature toggle-able, and a patch for
gnome-terminal that allows you to turn it off or on for a profile. I
filed a bug for this at:

https://bugzilla.gnome.org/show_bug.cgi?id=538195

You can get the patches there. Unfortunately, it looks like the vte
developer isn't very receptive to the idea of making the feature
configurable, which is kind of baffling to me.

The gnome-terminal patch makes the setting available under the
"Scrolling" tab in the profile editor.

Heath's comment and upstream bug suggest this is actually a VTE issue,
rather than screen, so I have marked the Screen task as Invalid and
added Ubuntu's VTE package and the upstream bugzilla report.

Thanks for taking the time to report this bug. Unfortunately we can't
fix it, because your description didn't include enough information. You
may find it helpful to read "How to report bugs effectively"
. We'd be

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Micah Cowan]

Please specify the versions of the libvte-common and gnome-terminal
packages installed on your system.

What exactly do you mean by "history scrolling"? Do you mean that it
scrolls through bash's command line history?

gnome-terminal should never send _any_ escape codes for mouse actions,
unless it has specifically been asked to. Something has asked it to. Do
you only encounter this action after running certain programs, or do you
have a customized .bashrc?

Please move any .bashrc you have, to a temporary location (where bash
won't read it by default, and open a new gnome-terminal. Does this
behavior still occur?

(Áron, I hope you don't mind if I assign this one to myself, again.)

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[PETERV]

I added termcapinfo xterm ti@:te@ to my .screenrc, and now I can scroll in my 
screen windows.  I love it.  Thank you.  I do have one question though.  If I 
use the mouse wheel, or the up & down arrows of the scrollbar, the window 
scrolls, but snaps back to the bottom by itself.  If I want to stay where I 
scrolled to I have to keep my mouse on the scrollbar slider and hold it in 
place.  Makes it kind of difficult to do a cut & paste.  Is there any fix for 
this?  Also, I know this is off topic, but is there any way to get syntax 
coloring in vim when you're using screen?  It works find outside of screen.
Thanks again

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Heath Caldwell]

The problem is with vte (the terminal widget that gnome-terminal uses).
A feature was added that sends a number of up/down keystrokes instead of
regular scrolling if it is using the alternate screen or scrolling is
restricted (one or both of which are the case when using ncurses
applications).

I wrote a patch for vte to make the feature toggle-able, and a patch for
gnome-terminal that allows you to turn it off or on for a profile. I
filed a bug for this at:

https://bugzilla.gnome.org/show_bug.cgi?id=538195

You can get the patches there. Unfortunately, it looks like the vte
developer isn't very receptive to the idea of making the feature
configurable, which is kind of baffling to me.

The gnome-terminal patch makes the setting available under the
"Scrolling" tab in the profile editor.

Heath's comment and upstream bug suggest this is actually a VTE issue,
rather than screen, so I have marked the Screen task as Invalid and
added Ubuntu's VTE package and the upstream bugzilla report.

Please specify the versions of the libvte-common and gnome-terminal
packages installed on your system.

What exactly do you mean by "history scrolling"? Do you mean that it
scrolls through bash's command line history?

gnome-terminal should never send _any_ escape codes for mouse actions,
unless it has specifically been asked to. Something has asked it to. Do
you only encounter this action after running certain programs, or do you
have a customized .bashrc?

Please move any .bashrc you have, to a temporary location (where bash
won't read it by default, and open a new gnome-terminal. Does this
behavior still occur?

(Áron, I hope you don't mind if I assign this one to myself, again.)

fwiw, you can make screen send scrollback to the terminal with this in
screenrc:

termcapinfo xterm ti@:te@

but I can reproduce the particular issue I mentioned with a fresh user
(which presumably doesn't have that option since it's not enabled in
/etc/screenrc).

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Micah Cowan]

Well, changing the TERM environment variable doesn't trick bash into
sending that sequence. Perhaps bash won't request it, but will interpret
them if they are sent unbidden.

Aha! If I run "screen cat", and scroll the mouse wheel, I get data. It's
definitely looking like screen automatically requests mouse input, then,
which it should not do. As I said previously, this is happening for me
in Feisty (screen-4.0.3-0.2ubuntu2).

I'm reassigning this to screen, as that appears to be the culprit.

Matthias, was screen involved when you experienced this bug? Otherwise,
the issue Chris and I have just been discussing would be a separate

mouse reporting to produce your issue).

Sorry, that wasn't very clear.

With the regular gnome terminal without running screen, the mouse
scrolls through the *scrollback* of the terminal (ie what you would
expect since the widget has a scrollbar). It's just running inside
screen that makes it scroll through command history, for me. Matthias -
can you reproduce it outside of screen?

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Micah Cowan]

For me, this happens in Feisty as well, though I suspect it depends on
the version of screen running (potentially, remotely)--or possibly bash
--rather than of gnome-terminal.

In order for such a thing to occur, bash must request screen to send it
mouse button events, and screen must in turn request it of the
"xterm"-like terminal running it. It seems likely that, for whatever
reason, bash does not enable mouse-button support when running directly
in gnome-terminal, but does when being run under screen. While it's hard
to say for certain, my strong suspicion is that this is a bash issue,
rather than a vte issue. However, as to whether this is truly a "bug",
I'm not sure.

Note that, scrolling through the scrollback buffer when screen is active
is useless anyway, since screen does not cause anything to be scrolled
in the terminal; rather, it saves things to its own scrollback buffer,
which can be accessed in "copy mode" (C-A C-[).

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Chris Jones]

I have just upgraded my laptop (Thinkpad X40) to gutsy in the last few
days and encountered this.

If I launch a regular gnome terminal and generate a lot of output (e.g.
ls -la /etc/) and scroll with the mousewheel it moves back and forth
through the history correctly.

If I then run screen inside the terminal and generate a lot of output,
instead of behaving as above, the scrollwheel just does the equivalent
of pressing up and down cursor keys - ie yes, it scrolls the command
history.

I am able to reproduce this with an entirely new user with no bash,
screen or gnome-terminal configuration. I am also able to reproduce it
with a python script which uses vte. FWIW, I scroll using the middle
mouse button and EmulateWheel (xorg.conf option). For me this is a
regression from Feisty.

ii  gnome-terminal2.18.1-1ubuntu

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Chris Jones]

fwiw, you can make screen send scrollback to the terminal with this in
screenrc:

termcapinfo xterm ti@:te@

but I can reproduce the particular issue I mentioned with a fresh user
(which presumably doesn't have that option since it's not enabled in
/etc/screenrc).

[Micah Cowan]

Well, changing the TERM environment variable doesn't trick bash into
sending that sequence. Perhaps bash won't request it, but will interpret
them if they are sent unbidden.

Aha! If I run "screen cat", and scroll the mouse wheel, I get data. It's
definitely looking like screen automatically requests mouse input, then,
which it should not do. As I said previously, this is happening for me
in Feisty (screen-4.0.3-0.2ubuntu2).

I'm reassigning this to screen, as that appears to be the culprit.

Matthias, was screen involved when you experienced this bug? Otherwise,
the issue Chris and I have just been discussing would be a separate
issue (though, I suspect some program would still have had to invoke
mouse reporting to produce your issue).

Sorry, that wasn't very clear.

With the regular gnome terminal without running screen, the mouse
scrolls through the *scrollback* of the terminal (ie what you would
expect since the widget has a scrollbar). It's just running inside
screen that makes it scroll through command history, for me. Matthias -
can you reproduce it outside of screen?

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Micah Cowan]

For me, this happens in Feisty as well, though I suspect it depends on
the version of screen running (potentially, remotely)--or possibly bash
--rather than of gnome-terminal.

In order for such a thing to occur, bash must request screen to send it
mouse button events, and screen must in turn request it of the
"xterm"-like terminal running it. It seems likely that, for whatever
reason, bash does not enable mouse-button support when running directly
in gnome-terminal, but does when being run under screen. While it's hard
to say for certain, my strong suspicion is that this is a bash issue,
rather than a vte issue. However, as to whether this is truly a "bug",
I'm not sure.

Note that, scrolling through the scrollback buffer when screen is active
is useless anyway, since screen does not cause anything to be scrolled
in the terminal; rather, it saves things to its own scrollback buffer,
which can be accessed in "copy mode" (C-A C-[).

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Chris Jones]

I have just upgraded my laptop (Thinkpad X40) to gutsy in the last few
days and encountered this.

If I launch a regular gnome terminal and generate a lot of output (e.g.
ls -la /etc/) and scroll with the mousewheel it moves back and forth
through the history correctly.

If I then run screen inside the terminal and generate a lot of output,
instead of behaving as above, the scrollwheel just does the equivalent
of pressing up and down cursor keys - ie yes, it scrolls the command
history.

I am able to reproduce this with an entirely new user with no bash,
screen or gnome-terminal configuration. I am also able to reproduce it
with a python script which uses vte. FWIW, I scroll using the middle
mouse button and EmulateWheel (xorg.conf option). For me this is a
regression from Feisty.

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[PETERV]

I added termcapinfo xterm ti@:te@ to my .screenrc, and now I can scroll in my 
screen windows.  I love it.  Thank you.  I do have one question though.  If I 
use the mouse wheel, or the up & down arrows of the scrollbar, the window 
scrolls, but snaps back to the bottom by itself.  If I want to stay where I 
scrolled to I have to keep my mouse on the scrollbar slider and hold it in 
place.  Makes it kind of difficult to do a cut & paste.  Is there any fix for 
this?  Also, I know this is off topic, but is there any way to get syntax 
coloring in vim when you're using screen?  It works find outside of screen.
Thanks again

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[John Dong]

It's almost certainly caused by screen -- the mentioned termcapinfo line
(also a variant is commented out in screenrc) "fixes" the problem. Maybe
we should consider shipping that by default :)

[Bug 106995] Re: gnome-terminal unconditionally interprets mouse wheel events

[Heath Caldwell]

The problem is with vte (the terminal widget that gnome-terminal uses).
A feature was added that sends a number of up/down keystrokes instead of
regular scrolling if it is using the alternate screen or scrolling is
restricted (one or both of which are the case when using ncurses
applications).

I wrote a patch for vte to make the feature toggle-able, and a patch for
gnome-terminal that allows you to turn it off or on for a profile. I
filed a bug for this at:

https://bugzilla.gnome.org/show_bug.cgi?id=538195

You can get the patches there. Unfortunately, it looks like the vte
developer isn't very receptive to the idea of making the feature
configurable, which is kind of baffling to me.

The gnome-terminal patch makes the setting available under the
"Scrolling" tab in the profile editor.

Heath's comment and upstream bug suggest this is actually a VTE issue,
rather than screen, so I have marked the Screen task as Invalid and
added Ubuntu's VTE package and the upstream bugzilla report.
