3-4 User Mode When Remote Console Mode is set to User Mode, the ATI video controller generates only the boot console. Following Linux booting, the NVIDIA graphics adapter generates both the Linux console and the Linux desktop. However, the Linux console cannot be viewed because the only means of viewing the NVIDIA-generated image is by using RGS. Because RGS requires that the X server be running, and because running of the X server causes the Linux console screen to be cleared, it's not possible to view the Linux console in User Mode. Figure 3-5 shows that the Linux console and Linux desktop are generated by the NVIDIA graphics adapter, but that only the Linux desktop is remotely viewable using RGS. The Linux console is not remotely viewable. However, Linux logins via ssh can be used to provide console-like access.

In User Mode, both the Linux console and desktop run on the NVIDIA graphics adapter- however, only the Linux desktop can be viewed (using RGS) because RGS operation requires that the X server be running, which clears the Linux console. Therefore, as noted previously, Setup Mode is recommended for Linux blade workstations. Blade workstation video subsystem 16
