I'm unable to access my Ubuntu 14.04 or Win XP partitions. When I try to log in to Ubuntu sometimes I get to the password point and my mouse stops working, or I get a black screen before that and nothing happens, and once I was able to log in but got a black screen after that.
I've tried various options such as recovery mode, repair broken packages, repairing GRUB (via boot repair on a trial Ubuntu USB), and I'm unable to run it in low graphics recovery mode.
After boot repair the url given was: http://paste.ubuntu.com/11213026
The splash screen is visible but moves so fast I'm unable to identify what issues there might be.
If I'm able to access a terminal screen what command can I use to diagnose the problem (and then how to fix it)?
I've been unable to access my (smaller) Win XP partition since doing the boot repair, so presumably that damaged the XP system and needs to be fixed as well.
I'm currently accessing the net via a trial Ubuntu USB.
I would really appreciate any suggestions, thank you.
Nvidia G72M graphics card, Quadro NVS 110M/Geoforce Go 7300 video controller, Ubuntu 14.04, Xfce interface, 32-bit, Dell Latitude D620M, Intel Core 2 processor 1.83 GHz, 2GB RAM
UPDATE (20/5): I realised it must be a graphics issue so tried a new driver. The nouveau one sometimes worked but has frequently been faulty.
I installed nvidia-346 (via xorg ppa instructions I found), which is working but is also faulty; it doesn't recognise my external monitor so I have to use laptop screen. Also my external speakers weren't recognised initially (no sound unless I disconnect them), but are now going again, and the splash screen script is very large.
When I choose XP it starts loading and then after a bit goes to a black screen, without the desktop ever appearing. I have no idea how to fix that.
sudo apt-get install nvidia-304
. Following this with the command suggested in the post I linked to above, 'sudo apt-get install nvidia-graphics-drivers-304gave "unable to locate package". Now my external monitor is recognised but not used even though it's ticked as the output. Is some kind of tweak needed (for Xfce interface?)? I ran
sudo apt-get update`. Trying to install nvidia-304-updates got "invalid operation" (I didn't purge anything first). – Lake May 19 '15 at 23:33
