Lenovo T500: No screens found

[jose1711]

On Lenovo T500 notebook I am getting this with NomadBSD 1.3:

[    32.349] (EE) No devices detected.
[    32.349] (EE)
Fatal server error:
[    32.349] (EE) no screens found(EE)
[    32.349] (EE)
Please consult the The X.Org Foundation support
         at http://wiki.x.org
 for help.
[    32.350] (EE) Please also check the log file at "/var/log/Xorg.0.log" for additional information.
[    32.350] (EE)
[    32.366] (EE) Server terminated with error (1). Closing log file.

Tried disabling syscons or using VESA but it's still the same. I was able to bring X up using X -configure but automatic detection would be nice.

Did the graphical setup start when you first booted NomadBSD?

[jose1711]

There are the following configuration options in BIOS (version 3.22), menu Config -> Display:

Graphics Device  [Integrated Graphics]
                 [Discrete Graphics]
                 [Switchable Graphics]
OS Detection for Switchable Graphics  [Disabled]
                                      [Enabled]

For NomadBSD to correctly configure and run X, the Graphics Device needs to be set to either Integrated Graphics (intel) or Discrete Graphics (radeon). Further, if the settings is to survive reboots OS Detection for Switchable Graphics needs to be disabled.

I have no idea how good the support for switchable GPUs is in FreeBSD but maybe a note to disable switchable graphics in BIOS if there are problems detected could make its way into the handbook.

Thank you for the feedback, @jose1711.

We will do so.

Could you please copy intel_setup and ati_amd_setup to /usr/bin, and copy initgfx to /etc/rc.d, and try to boot NomadBSD with Switchable Graphics enabled?

[jose1711]

Thank you, I will do so but it's going to take a while as momentarily I do not have access to this hw.

Copied the files from repository and reenabled switchable graphics. Now I at least get a text terminal (with both autodetect and VESA). Sadly, X are not working. Will provide more information - just tell me what to supply. Thanks.
