thinkpad R30 resolution problem / trident cyberblade 1l

[Jeffrey Seguerra]

When I installed Gutsy, xorg was able to give me 1024x768 resolution.

I installed Hardy Beta and my max resolution is only 800x600.

There should be one more option for 1024x768 for my ThinkPad R30

I do confirm the report of Jepong, I tested it on the latest Hardy Heron release with Toshiba Tecra 8200 (Trident Cyberblade).

Thank you for your report. Could you please attach the following log files: /etc/X11/xorg.conf, /var/log/Xorg.0.log. The output of: lspci -nn | grep VGA, sudo ddcprobe and xrandr.

Thanks in advance.

Reopen. Had the same problem. Requested output file attached.

I have this on my R30 using 8.10 release version. All requested files included.

Native 1024x768 is not available in the Resolution selection GUI. Instead I just get 800x600, 640x480, 400x300, and 320x240.

Here's a work around that will give you 1024x768 resolution (see attached xorg.conf), but the video acceleration is non-existent at any resolution. From what I have read, the acceleration issue is due to the xorg trident driver being crap. If I could code a new one I would, but alas, I cannot. Xfree86 had/has a good trident driver, but it's not the X server of choice anymore.

Just installed Jaunty Alpha 2. The problem persists in the default install.

[Ethan Bissett (draimus-deactivatedaccount)]

I can confirm the the workaround Wayne Towe posted does show the desktop in the right resolution.

[Ethan Bissett (draimus-deactivatedaccount)]

This is the xorg.conf with only the essential statements to get the right resolution on the R30.

Confirmed with 10.10 on a Toshiba R100.

01:00.0 VGA compatible controller: Trident Microsystems CyberBlade XP4m32 (rev 91)

Using the xorg.conf at this URL fixes it

SO the issue is that the trident driver does not correctly detect the available resolutions,

[Dirk F (fieldhouse)]

Confirm repeated with Xubuntu 10.10 on Toshiba Tecra 8200 (Trident CyberBlade/XP).

Xorg -configure segfaults, which may explain default to 800x600. Attached Xorg.99.log shows the backtrace after failing to open /dev/fb0.

Attached xorg.conf restores the correct default and choice of resolutions. It seems to be important to set XAA rather than EXA acceleration (=> blank screen).

Result for Lubuntu 14.04 on Toshiba Tecra 8200 (Trident CyberBlade/XP):

- 1024x768 is available with both trident and vesa drivers, at least if specified in the Monitor and Screen sections of xorg.conf (as previously attached for 10.10.)

Module vesa: vendor="X.Org Foundation", compiled for 1.15.0, module version = 2.3.3
