Hi everyone, I just finished the installation of 42.1 in my laptop (#2 below). I am now tweaking it to make it work. My installation was a clean install of 42.1 into a separate root partition from my root partition of 13.2. I installed by means of the install dvd which I downloaded. My home partition I am using is the same as the home partition I used for 13.2. First problem - the graphics driver - fixed (I think). It is an intel i915 card with a discrete nVidia GM107M graphics card. I installed bumblebee with the proprietary nvidia driver according to this: https://en.opensuse.org/SDB:NVIDIA_Bumblebee After that my system was able to boot into opensuse and kde. The hwinfo --gfxcard indicates that both the i915 driver and the nvidia driver are the ones installed. Second problem - KDE had a significant delay whenever I tried to do anything. When I clicked on any icon, I had to wait between 10 and 30 seconds for the application to give any indication that it is opening up. It didn't matter if it was kwrite, konsole, the kicker button, yast, or firefox or chrome. Also if I hit alt-tab to switch between applications, sometimes I would have to wait for that to switch also, and watch the desktop hang. I tried disabling desktop effects and switching the display backend driver to openGL something, and that seemed to help for about 1 minute, but then the delays and hangs would come back at random. I finally resorted to the following, and this is where my question is. Since I was using the same home partition as I was using for 13.2, I thought maybe there was some conflict between old KDE 4 files and whatever KDE 5 wanted to do. So I went into the /home/george directory and deleted all the hidden directories (that have a . in front). This included the .kde4 directory, .config, and .local. (I kept the ones I needed for applications like thunderbird). After I did that, I logged back into KDE, knowing it would re-create from scratch what it needed to run KDE 5, and voila, now the system works quite speedily, no more hangs. Pretty nice so far. Haven't really tested it extensively, but it seems much better. I am wondering if this is sort of standard practice when going to a new version of KDE? It seems that this should be written down somewhere. I saw several posts in the forums where others were struggling with similar problems of their system hanging, and there were suggestions of turning off desktop effects and disabling device acceleration, and other ideas. Thoughts? Would there have been a better way to make things work? -- George Box #1: 13.2 | KDE 4.14 | AMD Phenom IIX4 | 64 | 16GB Box #2: 13.1 | KDE 4.12 | AMD Athlon X3 | 64 | 4GB Laptop #1: 13.1 | KDE 4.12 | Core i7-2620M | 64 | 8GB Laptop #2: 42.1 | KDE Plasma 5 | Core i7-4710HQ | 64 | 16GB -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
