I finally could reduce the undo stack size from the DConf editor, but this changed nothing. That's not the keyboard, as everything is fine from Nano. The workaround I'm using, is to use Komodo.
So far: it's not due to the undo stack, nor to syntax colouring, nor to line length, nor to file size, although any of these may have an effect, the behaviour occurs also without any of these. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gedit in Ubuntu. https://bugs.launchpad.net/bugs/818642 Title: response to typing is very slow with code highlight with some files Status in Light-Weight Text Editor for Gnome: New Status in “gedit” package in Ubuntu: Confirmed Bug description: When editing files with code highlight mode set to "php" (maybe the same happens with other modes too), gedit sometimes is ridiculously slow to respond to typing. That is, when you type, the text you type appears with a very noticeably (and annoying) delay. This seems to happen with some particular files more than others, so I attach one particular file with which I experience the issue. I guess the issue is triggered by some syntax pattern. I have some much bigger files that don't cause any trouble when editing them, so it is not just a matter of file size. It is reasonable to expect that code highlighting increases cpu consumption, but definitely not that much. I've used a few other editors with code highlight and NEVER seen one become so slow even with files a lot bigger than this And even if computing the highlight had a critical cost, then more priority should be given to typing response than to computing the highlights, e.g. by only recomputing highlighting when the keyboard is idle for a given fraction of a second or (if this doesn't happen) every n-th character and not for every single character, etc ProblemType: Bug DistroRelease: Ubuntu 10.10 Package: gedit 2.30.3-1ubuntu1 ProcVersionSignature: Ubuntu 2.6.35-30.54-generic 2.6.35.13 Uname: Linux 2.6.35-30-generic i686 NonfreeKernelModules: nvidia Architecture: i386 Date: Sat Jul 30 22:35:40 2011 InstallationMedia: Ubuntu 10.04 LTS "Lucid Lynx" - Release i386 (20100429) ProcEnviron: PATH=(custom, no user) LANG=en_US.utf8 SHELL=/bin/bash SourcePackage: gedit To manage notifications about this bug go to: https://bugs.launchpad.net/gedit/+bug/818642/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
