>From time to time I've run into major problems upgrading KDE. In all cases they have been resolved by moving ~/.kde and letting the new version of kde build a new version of the directory. You'll have to reconfigure your desktop, but many of the config files can be copied over. For 4.4 > 4.5 I found that some of the Desktop effects settings were buggy after upgrade.<div> Paul <div class="gmail_quote">On Mon, Aug 16, 2010 at 9:34 AM, Jose Gomez-Dans <<a href="mailto:jgomezdans@gmail.com">jgomezdans@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Hi, I've just updated the system (10.4) to KDE 4.5 using the PPA backports archive. Update went fine, and I seem to have spotted a bumping of the kernel version during the update. The result is that now, after logging in through KDM, I get an akonadi error, and X crashes and I'm sent back to KDM. Looking at the logs, it may be related to drivers[1]. My graphics cards is this: $ lspci 00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c) 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) I installed ubuntu-desktop, and GNOME seems to work fine. I guess it may have to do with some of they eyecandy in KDE, but unsure of how to test it. Any hints? Jose [1] I guess, as sometimes, the system allows me to launch KDE's system settings, but crashes if I try to enable/disable or change the resolution of my external monitor.
