After updating from Ubuntu 14.04 to Ubuntu 15.04 the mouse on the workspace is too slow. With Ubuntu 14.04 it worked before. I tried to reinstall Ubuntu 14.04, but the same problem reoccurred. Needless to say, I reinstalled DraftSight several times on both versions, always the 64-bit. Can someone help me with this?

Mouse lags in Draftsight 2015 SP2, Ubuntu 14.04, Video Card Nvidia Quadro 600, Nvidia driver version 340.76.

Go to Nvidia X server settings; OpenGL Settings; and uncheck Sync to VBlank. Reboot, this fixed my mouse problem in Draftsight.

Here is solution for non-Nvidia cards.

I use Ubuntu 15.10 and have Intel GPU integrated. I don't use mouse, just touchpad. However, if you start Draftsight and than plug in a mouse after DS is already runnig, you can use the mouse normaly. Only zoom with wheel doen't work. Moving a pointer with the mouse works than normal and with the touchpad is slow.

Sorry, but I'm also looking to solve this problem.

The previous version installed DrafSight worked very well! I was forced to upgrade the program, because "this key/license no longer exists" or something like this.

I tried to force mouse decrease the DPI, no sucess.

After paying attention to the model screen, you can perceive there are TWO pointers/arrows working together: a square (from DraftSight) and the usual arrow (from Ubuntu).

Maybe find a way to "cut" this link, or just leave the usual arrow?

I'm using Ubuntu 14.04 in a notebook ACER i5 5750-6802, with Logitech M185 wireless mouse. Also, the touchpad works perfectly! But useless for CAD operations...

Tomorrow I will try a wired mouse...

For Intel integrated GPU and Linux Mint 17.2 (which is based on Ubuntu 14.04 LTS), running from the command line:

$ vblank_mode=0 /opt/dassault-systemes/DraftSight/Linux/DraftSight

works fine for DraftSight 2015 SP3.
