KDE 4.2 and qt 4.5?

wumpyr · n00b Joined: 20 May 2006 Posts: 70 Location: Downunder

I see that qt 4.5 rc1 as hit the tree. Is kde 4.2 + qt 4.5 recommended moving forward? or are things going to break? How much testing has really been done with this combo?

Some say yes, some say no. Plasma is not happy with some parts of Qt 4.5 at this time. Fixed probably later with 4.2.x and with 4.3 at the latest.

I am on KDE 4.2 and qt-4.5_rc1. It is working very well for me, the only problem that I have is that I can not add widgets to the desktop but then I had the same problem with qt-4.4. Other than that, plasma feels smoother (referring to the bug about system tray background not being transparent - that one is completely solved with qt-4.5).
I would say switch to 4.5 - just rebuild kdelibs, pykde4, qscintilla and all plasma related stuff.

In my experience plasma is even more happy with qt-4.5 as some bugs causing plasma to crash with 4.4.2 have been fixed.

Installed the qt-4.5_rc1 stuff overnight (after a bit of wrangling on bugzilla). It's messed up my fonts in KDE (spacing doesn't look right), not unusably so - I've rebuilt kdelibs and PyQT4 as advised by the new qt ebuilds - is there anything else that needs to be rebuilt to fix the fonts?

Also, the new qt and latest nvidia drivers (180.29) do not seem to like each other - direct rendering is on, but glxgears runs at 3fps and gl xscreensavers are equally painful. Reverting to the 180.27 beta driver appears to be fine though, oddly.

I may revert to qt-4.4 to check the nvidia-driver thing, and see if I get my nice fonts back.

I tried it too but it messed up my kdm. So I changed back.

One new problem with qt-4.5 - lancelot launcher does not work - if I click on Internet (for eg.) in Applications, I can not see the Internet Applications. The menu does not change, it still shows my favourites.

Thanks for this bug. We are monitoring this. Keep in mind ( and as i posted there ) that kde upstream is already aware of this

I've just installed qt 4.5.0_rc1. Now KDE doesn't want to run anymore. Kdm works and after login I see the splash screen and then: "The application Plasma Workspace (plasma) crashed and caused signal 11 (SIGSEGV).". I've allready reemerged kdelibs, PyQt4, plasma-workplace, plasma-apps and plasma-addons. What else?

Try rebuilding libplasma

Hm, libplasma is not installed at all.
I tried rebuilding libplasmaclock, didn't help.

Hello,

if i unmask qt-4.5 i get the problem that kdelibs are blocking. Please have a look:

Hi folks,
after updating to all those qt-*-4.5_rc1 packets i got some
strange errors:
-preview of files in dolphin crashes dolphin instantly
-buttons of my favorite plastik kwin theme disappeared(?)
-the middle mouse button does not work in konqueror
(for example to open an url in a new tab), while it does
in every other kde related application(?)

I already rebuilt @kde-4.2 and those packages like kdelibs/themes/styles/qscintilla/pyqt4.
I used the new "raster" USE flag. Any one having the same problems? Any hints?

Thank you in advance

Is it possible to get a list of packages that depend on qt to rebuild all of them?

Also note that "raster" is a new feature hence quite unteaster ( even though nokia says it is ok to use it ). You might want to disable it

Yet another post

@boris64

As I can see some of them are not fixed

Could you please open a new bug on us or kde bugzilla about the dolphin crash?

If you open it to our bugzilla make sure to assign it to qt_at_gentoo.org. Otherwise if you put it directly to kde bugzilla ( which I recommend ) could you
please paste the link here?

Thanks a lot
