is your open desktop really open ?#opensource #freelibreopensource

is your (free libre) open desktop really (free libre) open ?

this post was prompted by todays project which was to install GNU/linux natively on a HP elitebook notebook so i can run docker and access the @nvidia GPUs in @instaserver @foldingathome containers

phase 1 – install xubuntu

issues

  • NO VIDEO DRIVERS (just VGA)
  • NO WIFI DRIVERS (none nothing nada)

so try a bunch of usb wifi dongles

  • NONE OF THESE WORK

so lets connect notebook to our mobile via an ethernet cable (here’s how)

  • apt update
  • apt install aptitude
  • aptitude update

let try and get missing drivers

  • aptitude install synaptic
  • run synaptic
  • enable PROPRIETARY drivers !

YAY ! NVIDIA VIDEO and BROADCOM WIFI are auto detected

so

  • install the PROPRIETARY drivers

reboot

video and wifi now work

BUT NOTE I and this is the main point I NOW NO LONGER HAVE A FREE LIBRE OPEN SOURCE DESKTOP so I might have well left Microsoft Windows 10 running natively which is what i HAVE been doing for the last 5 years and would have kept doing if hadnt especially wanted to test docker & nvidia GPUs and @foldingathome.

So are you running an open desktop ?

If it is only semi (free libre) open why not run Windows 10 natively and run a TRUE OPEN SOURCE DESKTOP ENVIRONMENT inside Oracle VirtualBox or VMware Player ?

bizarro @HP and @Lenovo Intel i5 notebook 4GB DDR3L SODIMM memory problem

bizarro @HP and @Lenovo Intel i5 notebook 4GB DDR3L SODIMM memory problem

got some wierd crucial memory that crashes a HP EliteBook and a Lenovo ThinkPad notebooks

crashes on boot ! and fails memory test ! with the msg “Pa_sed” which i assume means FAILED ! bizarely works fine when “mixed” with a 2GB non crucial ram in a Thinkpad X220 and X410

so the mystery is what is the difference between crucial part no 171994 and no 313550 ?

every other param is IDENTICAL

  • 4GB DDE3L-1600 SODIMM 1.35V CL11 (171994  – B.M16FKD)
  • 4GB DDE3L-1600 SODIMM 1.35V CL11 (313550 – BJ.M8FP)

are @sainsburys £99 #lowspec @hp ac100na @microsoftuk #windows notebooks a waste of time and money ? #mktg #fail

are @sainsburys £99 #lowspec @hp ac100na @microsoftuk #windows notebooks a waste of time and money ? #mktg #fail

the sainsburys hp ac100na is a low spec intel celeron N3050 with 2G ram and 30G disk

it is almost impossible to upgrade it from windows 10 1709 to 1803 or 1809 but if you have 100 spare hours and follow these hacks you can however you may just prefer to try and return it to sainsburys or throw it away in your nearest WEEE recycling bin

hacks required to upgrade to windows 10 version 1809 on a hp ac100na

  • turn on flight mode (to prevent auto updates over wifi)
  • run disk clean-up (this takes around 4 hours each run)
  • select delete all previous versions
  • watch out for the nasty disk clean-up bug (see below)
  • reboot
  • ensure you have at least 12G of free disk space
  • turn off flight mode (to allow auto updates to kick in)
  • allow auto update to run
  • restart after a few updates have downloaded (do not wait for all updates to download or you will run out of diskspace)
  • hopefully these partial updates will get installed on restart

REPEAT the above steps until windows 10 1803 and windows 10 1809 have been installed

and if you get any windows 10 version 1809 0x80070002 errors DO NOT click retry but keep REPEATING the above steps until windows 10 1803 and windows 10 1809 have been installed

win1809fail

so if you havent given up and get lucky you should end up with a 1809 install confirmation screen

win1809

the nasty windows 10 disk clean-up bug

disk clean-up randomly injects a compress your drive option into list of folders to clean up so you cannot just tick all the folders without reading every one carefully

wincomp

footnote MOST but not all intel celerons are rubbish for example the intel celeron N2840 used in lenovo ideapad flex 10 is actually amazing and appears to be 10x faster than the intel celeron N3050

windows 10 and hp 8440w and hp 8560w hotkey support

make sure you re-install hp hotkey support to reenable screen brightness down, screen brightness up and ambient light sensor toggle hotkeys (F9, F10, F11)

YES that star with a triangle on the F11 key is the icon for the ambient light sensor toggle

hp & lenovo and #amd & #intel #memory bus nightmares

 

lost a few hours yesterday to some hp & lenovo and amd & intel memory bus nightmares started when i tried swapping DDR3 / PC3 / PC3L ram between an HP and two LENOVO notebooks

  • HP 255 G2 with AMD A4 memory bus FIXED at 1600Mhz
  • Lenovo T410 with Core i5 memory bus ONLY works at 1333Mhz
  • Lenovo Z50 with AMD FX7500 memory bus FIXED at 800Mhz

Basically the T41o refused to work with any of the other memory whereas i thought DDR3 ram was downwards compatible.

Actually just looking at my photos maybe PC3L is not downwards compatible with PC3 ?

modern notebook gotchas

modern notebook gotchas

  • UEFI
  • no recovery disks
  • 16GB USB stick or 24G external disk required to make a system backup
  • last hp i bought had no accessible hd or memory
  • last lenovo i bought only had only 1 memory socket soldered in despite space for 2
  • lots of preinstalled trialware (hp,lenovo,toshiba all guilty)
