mouse bug in 2.5?

[RoKenn]

I tried everything that I could to avoid using evdev now (also the stuff in the "attention ubuntu users" thread), experimented with both glx and sdl binaries and an empty ~/.nexuiz, setting only cl_maxfps, but everything to no avail. I even switched from Debian Stable to Ubuntu 9.04 beta.

I assume that my problem is not related to the evdev problem, especially since the symptoms are different. Not all mouse events are affected, only movements, and they are not delayed, but completely discarded.

My problem can be split in 2 parts:

(A) rare mouse movement failures. This happened with recent SVN versions and also with the final 2.5 release, if I disable cl_maxfps.
(B) extreme mouse movement failures. This happens with the official 2.5 release if I use cl_maxfps.

It is difficult to prove that (A) does not happen, because it might not occur for a long time.

I now found a solution that eliminates at least (B): I compiled 2.5 myself. The Nexuiz part is the 2.5 tag, Darkplaces is most recent. It seems the official compile cause the transition from (A) to (B).

I will check if (A) is still present with my compile, but I assume it will (which is also annoying).

Hey,

I think you said you got it working but how?? im techincally backwards so what did you do to get it to work???

I think you said you got it working but how?? im techincally backwards so what did you do to get it to work???

By just compiling it myself from the sources. Detailed instructions are e.g. at:
http://alientrap.org/forum/viewtopic.php?t=3061, although you might not want to do this, if you are "technically backwards".

And of course this applies only if you have exactly the same problem that I described, otherwise it's more likely to be the evdev problem, or even something different.

Wow, i am a idiot. The only problem was that my Nvdia driver wasn't up-to-date, i installed the new one from the link above and it worked out perfectly. I owe divVerent a huge thank you.

Thanks, krazygood.

krazygood: Glad its working now.

RoKenn: If you are running linux, in the glx version try the menu option 'Turn off OS mouse acceleration' in the Settings/Input menu.
For the SDL version you might try this in the console before starting Nexuiz:

Code: Select all

export SDL_VIDEO_X11_DGAMOUSE=0
export SDL_VIDEO_X11_MOUSEACCEL=1/1/1

Basicly i have s script does does:

Code: Select all

#! /bin/sh

export SDL_VIDEO_X11_DGAMOUSE=0
export SDL_VIDEO_X11_MOUSEACCEL=1/1/1

exec "$@"

Usage would be:
cd /path/to/Nexuiz
/path/to/Script ./nexuiz-linux-sdl.sh

Thanks esteel. Basically I tried all of that, although disabling DGA only for the glx binary.

The self-compiled binary is still working fine. It's basically 2.5 (the tag), only darkplaces is slightly newer (8835).

The question is what causes the difference between the official build and my build...

Today was a commit that MIGHT fix some mouse problems.. maybe it already did help you So 2.5.1 will be ok for you.

No, the commit is r8894, I still have r8835.

I tracked down the revision that caused this (8291), but it's fixed now. Works fine for me and tzork at least. So why not try it?

It's definitely not Nvidia related. Got that on Intel hardware too, but thought that integrated is too slow even to render menu properly in stable fps. However, reducing resolution made mouse movement both in game and menu even more jerky.
