Created attachment 528954 [details] Kernel log Hello. I have the old mobile video card Intel GMA X3100. lspci: 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 03) But with recent kernels and X drivers i have some problems. First of all, the kernel boot process is very slow. I see kernel messages, then i have some long delay, and after then the OpenRC starts. The same happens when i try to start X server (sddm). I have black screen and long delay. But when the X server has started, then it works ok. When i try "Ctrl-Alt-Fn" to get into the terminal, and then go back to X i also have some delay. The problem occurs with kernels 4.14.*, 4.15.*, 4.16.* I use the modesetting intel driver (not xf86-video-intel). In dmesg there are some errors: [code] [ 0.999459] [drm] Replacing VGA console driver [ 1.001213] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
