I have several SSD disks connected on my Ubuntu server, and under 19.10, they were mounted automatically under their respective directories. But under 20.04, every time I want to access one, it asks me for my password. It shows "administrator" in the file manager. Also the file system in the shortcuts in "other locations" all show like it is a network drive.

I have the following when I type the mount command:

/dev/sda1 on /vm type ext4 (rw,nosuid,nodev,relatime)
/dev/sdc1 on /data2 type ext4 (rw,nosuid,nodev,relatime)
/dev/sdd1 on /data type ext4 (rw,nosuid,nodev,relatime)
/dev/sdd2 on /ISO type ext4 (rw,nosuid,nodev,relatime)

And I have the following under /etc/fstab:

# /ISO was on /dev/sdd2 during installation
UUID=fb4ab474-a5a7-4226-8f91-80d9e9278fc7 /ISO            ext4    defaults,owner   0       2
# /data was on /dev/sdd1 during installation
UUID=f0492204-e674-475d-84af-72e59454af3c /data           ext4    defaults,owner   0       2
# /data2 was on /dev/sdc1 during installation
UUID=5572ea43-44dc-45d8-b5ec-942cfb4916c9 /data2          ext4    defaults,owner   0       2
# /vm was on /dev/sda1 during installation
UUID=c66fbf3d-76f6-4072-884a-eb440623ed40 /vm             ext4    defaults,owner   0       2

I made sure my newly created username is the owner of the whole disks and has rw rights.

I made a setup for development, and it downloaded a large set of .deb files. Now, I want to re-do this for a presentation, but I do not want to re-download the 400 files live. That would take too long. How can I get those files copied to /var/cache/apt and quickly reinstall them from local files. Will having the files locally avoid the download ?

I am looking at getting one of those USB-to-serial cables, but I just want to make sure it will work fine under Linux, before buying it. Is there a list of brand names or processor IDs that are known to work under Linux ?

I want to assign a special command to be executed when I press the F15 keyboard on a MAC keyboard under Ubuntu. This is the key on top of the PgUp key on the aluminium keyboard for Macs. I use that keyboard with Linux and I love it. In this case, I would like the F15 key to suspend the PC. The command for this is:

pmi action suspend

I used to play videos from MP4, wma files, as well as form DVDs, but for some reason, I can no more. The file gets loaded and the player starts, but it is always a black screen. No display at all.

What could go wrong ?

I used to have a monitor (Acer 20", AL2017) connected to the external video port of my laptop. Everything was great and I could get a rather high resolution available when setting it under Ubuntu (all versions). But since I connected it to a KVM, the monitor is no more recognized, and I cannot go beyond 1024x768.

My video adapter is an Intel chipset 9xx from an older Pentium Core 2 Duo laptop. The same monitor, using another video chipset (Intel 82G33/G31 rev 02) is properly detected through the switch box.

Looks to me like the video chipset is not the best, and I can live with this. I see that I have no xorg.conf, and I understand that I would need to generate one so I can then use it to force the available modes on the X system.

How can I generate the xorg.conf file for my Intel video chip, so I can use it then ?

Merci :-)

I have a card reader in my HP Mini netbook, but when I insert a card in it, the card is not recognised at all, and so not mounted. Does anyone know which kind of processor is used, and how I can get it working?

Thanks :-)

I have an HP Mini 110 series, and I see that anything that involves grahics or window management is getting very slow. I have the usual 1GB of RAM and the Atom N450 processor.

Is there any special driver I should find for the graphics processor?

Thanks :-)

I just got an HP Mini 110-3150, and booting from an external hard disk with Ubuntu 10.10 works all fine, except that there is no wireless detected. I noticed that the Wireless indicator is red under Ubuntu, but is enabled under whatever Windows 7 I got on it. So, I understand that it may not get detected at all by Ubuntu at startup time, and there is no manual switch that I can simply slide to turn on/off.

How can I get the Wireless device turned ON by default at startup time, and is there any special driver I need to install (proprietary or not) to get it working ?

Merci :-)

Update: When actually installing on the computer, as a new install, the NIC is not detected at first, but upon restarting, I get a notification of a closed driver available for the wireless. Once installed, updated and restarted, it works fine.

I have installed openssh-server from Synaptics, as usual, on a brand new Ubuntu Desktop computer, 10.10, with all updates and patches implemented.

If I have the local console logged in, I can SSH to the box, with no problem. If the local console is not logged in, I cannot SSH to the box. And If I have an SSH connection currently running, and log out of the local console, the SSH session will soon after be disconnected.

Looks to me like the network connection is only working when a user is actually logged in Ubuntu.

Is this normal behavior ? Is there a way to avoid this ?

Merci !

I am going to install Ubuntu on a brand new PC, which comes with some OEM installation of Windows 7. I know that Ubuntu can resize an existing Windows NTFS partition, so that it has free space to install. However, I am not sure how safe it is, and I'd like opinions, and tips'n'tricks on what I can do to avoid problems. The PC does not contain any data and I will have the recovery disk.

Merci!

I have installed OpenSSH server on my Ubuntu Linux box (10.04). I can SSH to the box properly, no problem. I have to use port 443/TCP. No problem accessing a shell prompt with PuTTY or other SSH client. Hoewver, when I try to use NX to have a graphical session, it is not responding. I thought that NX is simply using the settings used by /etc/ssh/sshd_config. Are there other parameters for NX that I should change so that it listens on port 443 ?

I use NX from nomachine.com, and the version of all components is: 3.4.0-5

Thanks :-)

I have a Toshiba USB floppy drive that I need to use under Ubuntu. When I connect it, and insert a floppy disk in it, I do not see anything mounted under Ubuntu 10.10.

I was suspecting the hardware and/or the floppy disk to be defective, and so I tested the floppy disk as well as the floppy drive itself under Windows XP, and everything was just fine.

I was able to find the following instructions:

• Add the following line to the /etc/modules file:

  floppy

• Enter the following shell commands:

  mkdir /media/floppy
mount -t vfat /dev/sdc /media/floppy -o uid=1000

This will mount the floppy, but I would like this to happen automatically, so when I connect the drive to the USB port, it automatically mounts the floppy.

How can I make this work? Or does Ubuntu only work with internal Floppy drives?

I have a DisplayLink-based external USB monitor, which has both power and data over USB, and seems to work perfectly under Windows 7, but only can display a text console under Ubuntu 10.10, and that I can only use when I am actually switched to it. So the only Use I can have so far is to have some text-based monitoring or console that I can watch while working on the graphic display.

I know there are some development done for DisplayLink, but I never could get it to actually run properly.

Yes, I tried the detailed setup described in other posts, but they did not work, and instead crashed my X that I had to restore.

Merci :-)

I have a laptop with an internal wifi G adapter, and I have an external USB wifi adapter that is compatible with N. the internal wifi can be disabled using a little switch on the side of the laptop. However, when I disable it using the switch, it disables ALL Wifi adapters, internal or external.

I want to use the external USB adapter, since it's faster.

Also, on my EeePC, I cannot seem to be able to disable the internal WiFi adapter. The blue light remains ON, which means I cannot use my EeePC in an airplane.

How can I fix those problems ?

Thanks :-)
