Hi,
I am using Mint 19 on a Sony Vaio VGN-AR520E and it has an NVIDIA Geforce 8400M GT. Right now, I am using the generic graphics driver. I tried installing the NVIDIA driver and the whole system stopped working. Tried a few times and to no avail and ended up having to reinstall Mint again.
I remember that this particular graphics card had driver issues for Windows 7 too. Is there a way to fix this? Also, the brightness control doesn't work; either using the function key or using the settings on the menu.
Any help would be greatly appreciated !
thanks

This may be due to what Nvidia calls MSI (Message Signaled Interrupts) compatibility problems. I’ve seen it affect some GeForce 8 series cards using the nvidia-340 driver.
To test this, use this command in the Terminal to open the grub file for editing:
Add the kernel parameter
So it will now look like this:
Use this command to update grub and reboot:
If that doesn’t work, then try this parameter:
If there is a problem getting back to the desktop, then press Ctrl+Alt+F1 to enter the virtual console tty1. Use this command to open the grub file:
Use the Arrow keys to move the cursor. Remove the parameter that was added. Press Ctrl+X to save and exit. Use this command to update grub and reboot:
To test this, use this command in the Terminal to open the grub file for editing:
xed admin:///etc/default/grub
Add the kernel parameter
pci=nomsi
to this line:
Code: Select all
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Code: Select all
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"
sudo update-grub; reboot
If that doesn’t work, then try this parameter:
NVreg_EnableMSI=0
If there is a problem getting back to the desktop, then press Ctrl+Alt+F1 to enter the virtual console tty1. Use this command to open the grub file:
sudo nano -t /etc/default/grub
