Bug Description

Binary package hint: syslinux

I tried installing Dapper on a PIII with a 3DLabs Oxygen VX1 video card.

With both the LiveCD and Alternate installer, I get the same result. Two lines are printed and then the screen turns black and everything stops. Ctrl-Alt-Del doesn't even reboot the computer.

The two lines are the SYSLINUX line and then a line beginning with 'Loading ...'

Colin Watson suggested holding the shift key while booting which should enable me to use text mode.

I will try this and report back if this works around the problem.

Holding the shift key bypassed the graphical bootloader and the installer worked correctly after that.

Note that for some reason the screen resolution was not set correctly and the installation progressed in 640x480. After the installation completed, I was able to have all the resolutions supported by copying the detected vertical refresh rate and horizontal refresh sync from /var/log/Xorg.0.log to the xorg.conf file.

For those of us who may not be quite as proficient with Linux - here is a little more detail (I just struggled through this tonight for about an hour myself and this bug helped me 80% of the way).

In your /var/log/Xorg.0.log file, look for the following lines:

.
.
(II) GLINT(0): Printing DDC gathered Modelines:
(II) GLINT(0): Modeline "800x600" 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync
(II) GLINT(0): Modeline "800x600" 36.00 800 824 896 1024 600 601 603 625 +hsync +vsync
.
.etc..

Copy all of these "Modelines" entries into the "Monitor" section of your /etc/X11/xorg.conf file, removing the "(II) GLINT(0): " part. For example, now the Monitor section of your xorg.conf file may look like this:

Section "Monitor"
 Identifier "NEC FE950+"
 Option "DPMS"
 Modeline "800x600" 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync
 Modeline "800x600" 36.00 800 824 896 1024 600 601 603 625 +hsync +vsync
 .
 .etc.
EndSection

However! This still did not work for me. I was not given any other resolution options after restarting X (and after restarting my machine). It turns out I had to specify the horizontal sync and vertical refresh ranges of my monitor as well. This information is also in the /var/log/Xorg.0.log file. For my monitor, I found these lines:

(II) GLINT(0): Supported additional Video Mode:
(II) GLINT(0): clock: 157.5 MHz Image Size: 356 x 267 mm
(II) GLINT(0): h_active: 1280 h_sync: 1344 h_sync_end 1504 h_blank_end 1728 h_border: 0
(II) GLINT(0): v_active: 1024 v_sync: 1025 v_sync_end 1028 v_blanking: 1072 v_border: 0
(II) GLINT(0): Ranges: V min: 50 V max: 160 Hz, H min: 30 H max: 96 kHz, PixClock max 240 MHz
(II) GLINT(0): Monitor name: NEC FE950+

I took the "Ranges:" line, found more information about the format of the xorg.conf file online, and edited my xorg.conf file further. Now the "Monitor" section of my xorg.conf file looks like this:

Section "Monitor"
 Identifier "NEC FE950+"
