I've had this problem for some time and it's driving me insane. What happens is that Firefox 5 will scroll really slow and sometimes even lag jump down the scrollbar. On top of that sometimes the sites will just lag while loading or scrolling in general. I've tried all sorts of setups to get this to work right. I just don't know what to do anymore. I'm getting to the point where I just may switch back to windows (which I really REALLY don't want to do). I originally thought it was a situation with flash but it doesn't seem to be the case. Therefore, there must be something else that is causing this.

This site in particular causes massive lag on my end with scrolling:

I have a feeling the problem with the scrolling has to be the Nvidia Proprietary driver. The reason I say this is because it works fine when using a live CD or when the system is on the Nouveau driver. I've tried disabling hardware acceleration, messing with compiz, reinstalling flash, and several other methods described on the web (lets just say I've been researching and at this problem for weeks). I've finally given up and I'm going to ask for help. Hopefully I get an answer here or elsewhere to this problem. :)

The scrolling problem may be tied to the fact that, sometimes randomly it will cause my system to halt (freeze) completely and I have to restart the system. The mouse is frozen and the system is unresponsive. Again, I have a feeling it has to do with the nVidia drivers. I want to point out that Chrome scrolls perfectly and has no issues (though I don't particularly like chrome and I shouldn't have to be forced to use it.) The system did flip out once with flash on chrome but not sure if that was just a random incident.

I'm desperate for a fix for this as I'm a recent convert to Linux. I absolutely love the system and I find it fun to use. Though this slight situation with something as simple as a browser is cutting into my patience.

Here is a link to my system specs (well not all of it obviously): http://xruptor.tripod.com/

Ubuntu 11.04 (64-bit), Nvidia driver (275.19)

are you using 32-bit or 64-bit Ubuntu? If you're using 64-bit, you may want to know that Adobe recently released a new beta version of 64-bit Flash for Linux that you may want to use instead of what's in the Ubuntu Software Center. – WarriorIng64 Jul 18 '11 at 20:04

Hi there and welcome. This is a question and answer site. You have at least two questions here - so can I suggest you edit this one to just describe your scrolling issue and create a second for your flash. Check this website for other suggested flash answers since they may apply to you. – fossfreedom♦ Jul 18 '11 at 20:05
If the issue is caused by the nvidia driver, consider removing / disabling the proprietary driver. – Lekensteyn Jul 18 '11 at 20:17
@WarriorIng64: I posted my specs above as a link. I'm sorry I should have posted that in the original question. I'll go ahead and make the changes. I have the latest version of flash 64bit installed and it hasn't help with the scrolling issue. I figured it may have been tied to the problem but it could be something else. – Xruptor Jul 19 '11 at 16:09
@fossfreedom: I figured the flash issue may have been tied to the problem. After some careful updates and commands the situation hasn't improved. It's safe to say that it isn't flash but something else. The scrolling problem hasn't been resolved and it's still causing severe lag with certain sites. I will edit the question as you requested but I felt it would help with the situation. – Xruptor Jul 19 '11 at 16:11

Nope sadly it didn't help the situation. I've reinstalled Ubuntu thinking it may have been some sort of conflict. Turns out everything was fine until I installed the proprietary drivers. Since I need to use those because I play games on WINE, I'm left with no alternative other then using Chrome. It appears I'm one of the very few who experience this problem. Even so I doubt this will ever get resolved. It's apparent to me now that FireFox has grown in to a bloated piece of software. It used to work just fine in the past on my linux machines. Shame too always thought it was useful. – Xruptor Aug 18 '11 at 12:03

This seems to be a discussion of the problem:

Well it seems this is a major issue with Firefox and Nvidia. It's a known problem has been documented on several bugs on Launchpad. There is no known fix yet.
