Hi guys

If "text mode" means as shown on a virtual terminal (typically accessed by Ctrl+Alt+F1 through 6 or Shift+Ctrl+Alt+F1 through 6) then passing a vga= kernel parameter from the boot manager (LILO or GRUB) according to the following table may do what you want:

Code:

# +----------------------------------------------------+
# Colours |  640x480    800x600    1024x768   1280x1024
# +-------+--------------------------------------------+
#     256 | 0x301=769  0x303=771  0x305=773   0x307=775
#     32K | 0x310=784  0x313=787  0x316=790   0x319=793
#     64K | 0x311=785  0x314=788  0x317=791   0x31A=794
#     16M | 0x312=786  0x315=789  0x318=792   0x31B=795
# +----------------------------------------------------+

If "text mode" means in a terminal emulator running under X then configuring the terminal emulator will do what you want. Details will be specific to the terminal emulator.

The vga= kernel parameter is deprecated if you use a driver that support kernel mode setting (KMS), which is nowadays every open source driver.
Use the video= option instead, for example

Code:

video=1280x1024@60

This will set the resolution to 1280x1024 at 60 Hz.
