[SOLVED] Linux Mint 11 - Problem using Live DVD

[athspk]

I have 2 machines, a Laptop and a Desktop with the following specifications:

Code: Select all

-------------------------- LAPTOP -----------------------------
Processor:      Intel(R) Core(TM)2 Duo T8100  @ 2.10GHz
RAM:            2,00 GB
Graphics:       NVIDIA GeForce 8600M GS - 512MB

-------------------------- DESKTOP -----------------------------
Motherboard:    Gigabyte EP43-DS3L
Processor:      Intel(R) Core(TM)2 Quad Q9550 @ 2.83GHz
RAM:            4.00 GB
Graphics:       NVIDIA GeForce 9800 GT - 1GB

I downloaded and burned linuxmint-11-gnome-dvd-64bit.iso.

I tried it Live on my Laptop and worked fine. I loved it

The problem appeared when i tried the same on my Desktop:
I reached successfully to the point where casper loads:

Code: Select all

Loading casper/something..........................
.........................................................
Loading casper/something_else....................
.........................................................
.........................................................
.........................................................
Ready.

After that, the screen goes black and i get a "No Signal" from my Monitor.
I waited 10 minutes just to see if anything happens, but nothing.
By pressing the Reset button on my tower, i repeated the process 3 times, but the problem remains.

Has anyone encountered the same issue?
Please advise. Thanks in advance.

During the countdown screen during boot, press a key. Then highlight the second option in the menu (compatibility mode), and press Tab key to edit the boot parameters further. Add the following before the -- on that line: acpi=off nomodeset nolapic

See if this allows you to boot, or at least get some error. The problem is usually with the graphics card (hence the nomodeset), but might be with other parts of the hardware (hence to other options).

Usually it are the laptops that give the problems, not the desktops

Hi Vincent,
I tried what you told me and it worked.

Since you proved that the problem was my graphics card,
am i going to have problems with it ?

Thank you for your help!

Just install Linux Mint first, and after install run all the updates. To do that, open Update Manager (shield icon in your bottom bar) and repeat doing updates until all installed. If after reboot you still have problems, you might then check to see if you can install drivers from Menu -> Control Center -> Additional Drivers.

If after installation you initially have the same problem, hold shift during boot to show the GRUB boot menu. Then press 'e' to edit the boot parameters (yes, different from the Live DVD), scroll down to the line that stats with "linux" and replace "quiet splash" on that line with "nomodeset acpi=off" (without the quotes).

Probably you can resolve this by installing (which loads hardware specific drivers), or doing all the updates (which might patch those drivers to better version), or loading the additional driver. If this all fails, we can make the "nomodeset" option permanent.
