Bug description:
[Impact]
On some I+N configs, It will take about 90+ seconds to open the 'Nvidia
settings' window when 'Power Saving mode' running.
[Fix]
do not read config file if Nvidia driver did not loaded:
change nvidia-settings/src/nvidia-settings.c
if (!op->no_load) {
ret = nv_read_config_file(op, op->config, op->ctrl_display,
p, &conf, &systems);
to
if (!op->no_load && systems.n != 0) {
ret = nv_read_config_file(op, op->config, op->ctrl_display,
p, &conf, &systems);
[Test]
1. Install Ubuntu image.
2. Boot and login the system.
3. Open 'Nvidia Settings' app
4. Select the prime is 'Power saving' mode
5. Reboot system and login
6. Open 'Nvidia Settings' app
7. Verify the result
[Where problems will occur]
the "systems.n" gets from
NvCtrlConnectToSystem(op->ctrl_display, &systems);
If there is a possibility that systems.n is zero and we still need to read
nvidia config file, then it will be a problem. I tried and cannot find a
situation like that.
