    Have you tried to disable hardware acceleration in FF settings?
  2. Re: Program crashes, filesystem write protected

    The problem with SSD's and adapters is, that TRIM usually not work with adapters (definitely not with the IDE/PATA interface). Some USB adapters support the UASP which implies TRIM, though.

  3. Re: Program crashes, filesystem write protected

    The system drive is mounted with the option "errors=remount-ro" which means that if errors occur on the volume, it is remounted as read-only. This may be the cause of your problem and I would suggest...

    [ubuntu] Re: dd command for creating iso file.

    You are probably right. I've not been into Windows for a long time and I was not aware if there was such a thing as "Windows Lite" with limited space usage ;)

    [ubuntu] Re: dd command for creating iso file.

    In your command, dd sees /dev/sdb1 as a file with the size 7.3GiB. Had the USB stick been 64GB so would the image created therefrom with dd. The dd command will not remove unused space, you need...
  7. [SOLVED] Re: Encryption recommendation for external drive with data

    Yes, you can "matryoshka doll" your encrypted containers, but that would make very little sense. Understanding the encryption parameters and how they impact the security of the encrypted data will be...
  8. [SOLVED] Re: Encryption recommendation for external drive with data

    I had this post once and in that particular case default mount options had a performance impact of more than 50%. I did also try with noatime but that had much less impact than mounting as read-only....
  9. [SOLVED] Re: Encryption recommendation for external drive with data

    Ubuntu uses the default mount options unless you tell Ubuntu to do something different. In the first picture, you have mount options for the file system at the bottom, entering "noatime" into that...
  10. [SOLVED] Re: Encryption recommendation for external drive with data

    For some file systems, file access time is enabled by default which means that each time a file is read from, the driver writes back to disk in order to update the files access time. By (manually)...
  11. [SOLVED] Re: Encryption recommendation for external drive with data

    I disagree. If one would try to access an encrypted volume, the usual approach would be to run through a list of well known passwords. If that does not give access, brute force may be one of the next...
  12. [SOLVED] Re: Encryption recommendation for external drive with data

    I would strongly encourage you to NOT use a passWORD but instead use a passPHRASE! An example of a strong passphrase could be: "in the field there are 2 cows and a sheep". It is easier to remember...

  15. [SOLVED] Re: generate random number inset into text file

    newseed=$((1 + (($RANDOM * $RANDOM) % 2147483647)))

    It would be quite nice if snap / snapstore / snapcraft was an optinal install in the *buntu system installer. However, in Kubuntu Discover you can clearly see which source a package is (or will be)...

  20. [SOLVED] Re: Ubuntu installer doesn't see external SSD connected via USB

    Not that it would cause the drive to be unavailable, but beware that some cheap SATA=>USB3 adapters / enclosures work very poorly with Linux since UASP support is broken and TRIM is not available. I...

    [SOLVED] Re: dd clone not working all of a sudden

    On one card 4GB means 4GiB ( 4*(1024^3) ) and on another card it may actually mean 4GB ( 4*(1000^3) ), so you should check how many bytes the card(s) actually contains: 4GB ~= 3,7GiB. Also cheap or...

    Re: udev rule for USB device not working

    Mode may be changed after your rule is used, try to set the mode as final with MODE:="0666". You may also want to add either an owner or a group to the rule.
