Hi,

for a better understanding: x2go uses NX and NX is optimized for the X11 protocol, reducing both bandwidth and latency. Recent firefox releases do not use that protocol anymore to display their windows and content. This means that NX has to handle everything Firefox draws as images, which is far less efficient (instead of transferring the command "draw a circle here with radius 100 and this pen" it has to grab the area where firefox draws the image and transfer that area as graphics to the other side). AFAIK Palemoon still uses the X11 protocol and therefore still benefits from NX. x2gokdrive does not use NX technology at all but concentrates completely on transferring graphics only. While this guarantees better compatibility with current Xorg server versions (x2gokdrive is derived from a current Xorg version while NX is derived from a much older version) I assume it also requires more bandwidth.

Instead of switching to Palemoon you might want to experiment with the line speed and/or compression settings in x2goclient. For some insights see here: https://github.com/ArcticaProject/nx-libs/issues/802

Some time ago you could also disable smooth scrolling in Firefox (open about:config and search for "smooth") which might help in the current situation, too, but I am not sure if Firefox siullt offers that switch.I also recommend an extension like https://addons.mozilla.org/en-US/firefox/addon/disable-transitions/ to disable some bandwidth intensive sugar in firefox (e.g. gradient greying of backgrounds while cookie banner pops up).

Hello Stefan,

Thank you for the great tip. Pale Moon really runs a lot smoother.

Would that work much better with KDrive than this combination with PaleMoon?

If I can optimize this a bit, then I could save myself the switch to LTSP that was actually planned for this reason.

Greeting, Olaf

I've been using x2go for a long time and I've always had the problem of jerky scrolling on websites.

In the meantime, however, I use cloud services in the browser, and now another one is added. This is practically no longer usable with my x2go installation.

Is there a combination (Linux OS + browser) that runs really fast? Videos aren't important, but modern websites shouldn't be stuttering.

For classic, NX-libs based X2Go, you should use Pale Moon instead of Firefox or Chrome. If you're willing to run X2Go nightly builds, you can switch over to X2Go-KDrive, this should give you better browser performance for Firefox and Chrome. (KDrive should become stable Real Soon Now TM, but at the moment, it's only available via our nightly builds.)

Kind Regards, Stefan Baur

Sorry to hear that. Unfortunately I don' know anything about x2godrive support. x2gokdrive is derived from a recent Xorg server (and kept uptodate, AFAIK) so probably it supports anything that runs on a current Xorg server.

Hi Stefan & Uli!

Unfortunately, it has now turned out that Pale-Moon is not compatible with one of the websites that I absolutely need. The drop down menus included there freezes the browser for a long time as far as I can tell. Since the Pale-Moon forum hasn't been available for a long time and I don't see any other support, I can't get any further.

Uli, Thank you for the information about the differences. Due to the stuttering in browsers, I have made several attempts with the settings in the past, but had no significant success.

Does x2goKdrive work with the TCE? Then Kdrive would be my last chance with x2go and I would try it out.

Greetings, Olaf

Sad. I completely missed the forum having issues. However, you could try shooting Moonchild an E-Mail - not with your tech support question, but asking where to ask for tech support in the meantime while the forum is down.

I've created X2Go-TCE-Live builds with KDriveclient included in the past, and we used them at several events to demo X2Go-TCE.

I can't speak for X2Go-TCE-NFS, but would expect that it should work, too.

At the top of their website there is now a notice of a server failure. And since somewhere on the website it is explicitly mentioned that users shouldn't send questions about technical things by e-mail, I refrained from doing so.

Yes. That is why I said you shouldn't ask for tech support, if you try to contact him, but rather ask where to ask for it while the forum is down.

I tested again several hours on my ESXI and on a local PC + Clients with several new VMs with Ubuntu, Lubuntu, Bodhi, ... and different browsers, but everyone except Pale-Moon stutters.

Yes. This is a browser issue, nothing the distributions could fix.

What is the easiest way for me to test x2goKdrive? There was an email regarding the release, but unfortunately I can't find it in the source.

Which Linux distribution and version are you looking to install?
