no brightness control on my vaio with nvidia driver installed
by Pierre032020 from LinuxQuestions.org on (#50NP8)
Dear,
I have an old laptop vaio fz31z with a nvidia geforce 8600m gs graphics card.
I reinstalled linux mint cinnamon 19.3 recently with the default "new" graphics drivers :
No problem with the brightness control with the fn+F5/F6 keys.
No problem with the brightness control in the taskbar.
Since I installed the nvidia drivers :
the fn+F5/F6 keys no longer work.
There is no longer an icon in the taskbar to adjust the brightness.
The brightness is at maximum at each start up.
This problem is not new on my PC, but I didn't use it much in linux because I had a dual boot with windows, it didn't cause me any problem.
There were many distributions installed on my pc (new instllations): ubuntu, xubuntu, linux mint mate, linux mint cinnamon, linux mint xfce.
On different versions (12lts, 14lts, 16lts, 18lts). The problem exists on each version.
Today I want to fix the problem because I use this pc daily on linux mint.
There are a lot of posts on the internet about this problem, but none of them worked for me.
Although I use linux regularly, I'm not good for the command line and I don't necessarily know what I'm doing when I'm doing tutorials.
Can you please help me?
