No, this only sets the tty resolution; the resolution of the X server
appears to be limited to the maximum as specified at line 123 in
drivers/gpu/drm/drm_crtc_helper.c:
drm_add_modes_noedid(connector, x, y);
kernel parameter TTY resolution Max. X resolution
- 640x480 1024x768
vga=0x31b 1280x1024 1024x768
video=1280x1024 1280x1024 1024x768
video=1280x1024 vga=0x31b 1280x1024 1024x768
drm.noedidres 1280x1024 1280x1024
drm.noedidres vga=0x31b 1280x1024 1280x1024
