this is another episode of “GNU Linux saves old hardware from the dumpster”

strange (GHOST IN THE GPU) anomalies have been spotted

strange (GHOST IN THE GPU) anomalies have been spotted X-D

the good:

  • IT JUST WORKS 🙂
  • the onboard GPU can actually display the full resolution of a 19″ display (1920×1080) of the Gnome2 MATE Desktop

the bad:

  • the working speed is (obviously) not the greatest
  • boot time is like: 15sec for BIOS, 60sec for GNU Linux Debian 10 MATE (to Desktop) (refused to detect OCZ SSD so installed a Model Number: SAMSUNG SP1614C 160GB (also old and slow)

benchmark:

  • benchmark_md5sum.sh (the time it takes to compute md5 checksum of a 1GByte file full of zeros, so a combination of harddisk and cpu) completed in real 0m44.214s (0m24.353s for the computing)
