I've been working to get KDE up to speed for 7.7 and have finally finished the core modules. I did have a problem at first when I was testing. I want to document the issues.
My video is NVIDIA Corporation NV37GL [Quadro PCI-E Series]. When I configure the kernel, it wants to use the nouveau kernel driver. When the system starts up, it was going into framebuffer mode, but it was giving me problems. The cursor was disappearing often. For instance going into vim and exiting caused it to disappear every time. Executing a terminal reset (echo -e \\033c) brought it back, but only until something else ran. When entering X, twm was OK, but KDE was giving a lot of weird hashed colors and the startup hung. What I found was that adding nomodeset to the kernel command line fixed both the text mode problem and KDE, but KDE performance is poor. My kernel configuration has CONFIG_DRM_NOUVEAU=y CONFIG_NOUVEAU_DEBUG=5 CONFIG_NOUVEAU_DEBUG_DEFAULT=3 CONFIG_DRM_NOUVEAU_BACKLIGHT=y In KDE, the resolution is 1024x768 even though the monitor is 1366x768. It looks like NOUVEAU is completely disabled: [ 1117.328] (II) VESA: driver for VESA chipsets: vesa [ 1117.328] (--) using VT number 8 [ 1117.338] (EE) [drm] KMS not enabled Reenabling modeset on the kernel line allows twm to come up and the nouveau driver appears to give normal results in twm. I don't particularly want to disable Nvidia/Nouveau support, but I suppose I could and use the proprietary drivers. I don't recall the problem in earlier kernels, but I'm not sure. If anyone has any ideas about the apparent interference between the nouveau drivers and KDE, please let me know. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
