I'm not sure where to put this topic so I'm putting it here. Please move it to another, more suitable section if there is one.I installed VL 7.1 Light on my old desktop PC yesterday. I have to say I'm amazed, it's quite more lightweight and faster than Lubuntu or Windows XP. Anyway, here is what the problem is.
The only thing I did after installing is upgrading the system. I opened Gslapt Package Manager (not sure is that it's name?) and clicked
Update. After that, I clicked
Mark All Upgrades and finally
Upgrade. Oh yeah, I almost forgot. I also removed all the packages in the excluded list from it (i.e. made excluded list empty) before upgrading, so I can have all my packages up to the latest version.
Everything worked fine until I powered off the PC. When I turned the PC back on, I couldn't move the mouse nor type anything with the keyboard (both mouse and keyboard are USB) so I couldn't even log in. I have two kernels (3.18.16 and 3.18.44) but switching them doesn't help. Luckily, TUI versions of both kernels do work (TUI variants of their GRUB entries, to be precise).
I chose Linux 3.18.44 TUI and logged in as root. The keyboard in TUI version does work (obviously, since how else could I log in?) but I wanted to check the mouse. I executed
startx and X started. I tried moving my mouse and some keyboard shortcuts but nothing happened. I had to use the power button to shutdown the computer. Tried the same thing with 3.18.16 TUI but it was completely same.
Then I decided to try some other USB devices (the only one I have is flash drive, so that's the only one I could try). I plugged in the flash drive in the port and executed
lsblk. It wasn't detected. Then I tried
lsusb but that returned:
unable to initialize libusb: -99I also noticed that my friend left his PS/2 keyboard, so I decided to try it too. The same happened as with the USB one: works in TUI but not in GUI.
So... what can I do to further troubleshoot and maybe fix this problem? Is it possible to easily downgrade packages? I know that Arch (I use Arch, btw

) stores previous versions of packages in
/var/cache/pacman/pkg/, so when I want to downgrade I go there and run
pacman -S package-to-downgrade.pkg.tar.xz If Slackware (since VL is based on Slackware) has something similar I can just go there and run
upgradepkg * since I upgraded only once so the all packages in that directory must be the previous versions of the current upgraded packages (of whom the one or more is causing me problems).
Any help is appreciated!!!

PS: Why is there an error "
Sorry, you are not allowed to post external links." if I include
code tags in my post? Is that normal?
