I can confirm that the problem persists in oneiric with xfce4-terminal 0.4.8-1. However applying my old patch to the current source and installing the result fixed the problem for me.
To recap: 1) Ubuntu compiles libvte (Source package vte) with some patches, one of them is the 93_add_alt_screen_scroll_toggle.patch, which makes the "scroll alternate screen with mouse"-feature runtime configurable. In upstream, the feature is always on, this patch makes it off by default but the feature can be turned on by an appropriate method 2) xfce4-terminal in oneiric (0.4.8-1) comes without any patches to upstream. As upstream does not use a patched vte, they of course did not merge ubuntus fix for the alternat screen scroll. 3) Applying my patch below adds a hidden (i.e. can not be set by GUI controls) configuration item ScrollingAlternateScreen, so entering the line ScrollingAlternateScreen=TRUE in ~/.config/Terminal/terminalrc will tell xfce4-terminal to switch the scroll alternate screen feature on. 4) Apparently xfce4-terminal reconfigures itself when ~/.config/Terminal/terminalrc is edited while it is running, so I can confirm that entering the line with FALSE will switch off alternate screen scrolling and reverting back to TRUE switches it on again. The feature can easily by tested by using less as a pager, then calling man bash (or any sufficiently long manpage) and activating the scroll wheel in the window. IMHO, the vte patch 93_add_alt_screen_scroll_toggle.patch is done wrong: Making an upstream feature (alternate screen scroll) configurable may be a good idea, some people may not like it, so it's a matter of personal preferences. But making it switched off be default, and by that changing all applications (terminal emulators) that depend on the lib is clearly wrong. ** Patch added: "Patch to enable scroll alternate screen" https://bugs.launchpad.net/ubuntu/+source/xfce4-terminal/+bug/358796/+attachment/2700051/+files/10-scroll-alternate-screen-configurable.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/358796 Title: mouse scroll in xfce4-terminal when running vim (man, info) doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-terminal/+bug/358796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
