frozen screen after SIGKILL to Xorg

My Xorg freezes often (approximately 1 time a day), so I kill it with Alt+SysRq+K. Then a strange thing happens. I see a blank screen or a text (a piece of a text previously seen). My computer is responding to my keyboard. E.g., I can switch to virtual terminal 1 and play some music. I type commands blindly, they do not appear on the screen, the screen is static. "chvt 1", "clear", Alt+SysRq+V, Alt+SysRq+G do not change the screen. However, I can print on the screen by "cat $SCREENSHOT > /dev/fb0". It seems that the framebuffer is working but my "bash" is not connected to it.

I thought this is an issue with my video driver ("nvidia") but I see the same with "vesa" and "nouveau". Except that with "vesa", I see random pixels instead of a text mode. So, I want a normal text virtual terminal after killing Xorg with SIGKILL. Is it possible? Does somebody have it working?
