Hi,

I'm using KDE 3.5 for "terminal services" for several tens of clients. I use nxserver - freenx on the server side and nxclient from 2x on the client side.

Since few days I'm trying to set up KDE 4 in testing environment and to reach usability/speed the same as on 3.5. In KDE 4 I don't see any option to decrease (lock down) visual effects. When all visual effects are on, nxserver has to send enormous quantity of information so the performance suffers a lot. Server machine is loaded 3-4 times more than when using KDE 3.5 (this is all encrypting and compressing more graphics in nxserver). FOr example resizing an icon effectively hogs a 2MB/s link.

I would like to have kind of lock down editor so I can trim my KDE for users so they are unable to put on every visual effects and later complain about the performance. And even more: I need a schema which is as limited as KDE 3.5 with almost every effect disabled (those ones accessible through "Desktop Settings Wizard").

I perceive this is serious issue, as using KDE 4 as terminal services in business is not an option now because of its requirements (KDE 4 through nxserver effectively kills every modern machine/link).

Best regards and I'm looking for a (satisfactory!) reply!

Janusz.

Sorry I reported to Konqueror; I had to choose some main package as this is true for "whole" KDE 4.

Hi,

This bug represents longtime and major problem for most KDE users.
Terminal sessions are not alone, "none"/"weak" GPU users with MIDs/Netbooks/NetTops are in same boat...

It's really a loss that KDE developers dealing with much-much-much less important things like Social blogging, multiple browsers, useless widgets and etc. How much time you spend looking on you desktop surface? A second before you really starting to use DE?

Visual performance and infrastructures must be #1 priority for DE.

FYI: By just replacing default(Oxygen) visual style with GTK+ style, I've gained serious improvement.

P.S. Hope I didn't hurt anyone's feelings, but we are desperate while looking for salvation.

Is this possibly a duplicate of Bug 163001?

Setting in my .bashrc :

export QT_GRAPHICSSYSTEM=native

solved this problem during several years.

(Unfortunately, it no longer works with Qt5 and FreeNX is unusable with Qt5/KDE5/Plasma)

I guess it's no longer a problem then, if the affected software hasn't worked in years.
