yes, but in the log there is not useful info about of the reason such behaviour. Only after starting of X
from remote computer by ssh I could read the reason in console
X: symbol lookup error: /usr/lib/xorg/modules/drivers/radeon_drv.so undefined symbol:
DrmCheckModeSettingSupport
after ldd /usr/lib/xorg/modules/drivers/radeon_drv.so I discovered that I have old version of libdrm
in /usr/lib
and new version in /usr/lib/i386-linux-gnu/libdrm.so.2
I manually removed old lbdrm from usr/lib/ and after that I have
ldd /usr/lib/xorg/modules/drivers/radeon_drv.so
linux-gate.so.1 => (0xb76f4000)
libpixman-1.so.0 => /usr/lib/i386-linux-gnu/libpixman-1.so.0 (0xb7530000)
libdrm_radeon.so.1 => /usr/lib/i386-linux-gnu/libdrm_radeon.so.1 (0xb7528000)
libdrm.so.2 => /usr/lib/i386-linux-gnu/libdrm.so.2 (0xb751a000)
libpciaccess.so.0 => /usr/lib/i386-linux-gnu/libpciaccess.so.0 (0xb750f000)
libudev.so.0 => /lib/i386-linux-gnu/libudev.so.0 (0xb74ff000)
librt.so.1 => /lib/i386-linux-gnu/i686/cmov/librt.so.1 (0xb74f6000)
libc.so.6 => /lib/i386-linux-gnu/i686/cmov/libc.so.6 (0xb7399000)
libm.so.6 => /lib/i386-linux-gnu/i686/cmov/libm.so.6 (0xb7372000)
/lib/ld-linux.so.2 (0xb76f5000)
libz.so.1 => /usr/lib/i386-linux-gnu/libz.so.1 (0xb735b000)
libpthread.so.0 => /lib/i386-linux-gnu/i686/cmov/libpthread.so.0 (0xb7342000)
Now X starts without any problem
Question - is it possible to see such very important errors as I had
X: symbol lookup error: /usr/lib/xorg/modules/drivers/radeon_drv.so undefined symbol:
DrmCheckModeSettingSupport
in xorg log ? It will drastically decrease the time for finding out of the problem.

ah - it was a lot of upgraded packages - several hundreds. I didn't save the list of them
thank you for your hint about stderr on remote computer
