Red Hat Bugzilla – Bug 59569
GUI install hangs with trident Cyberblade
Last modified: 2007-04-18 12:40:14 EDT
I have a Compaq laptop with a Trident CyberBlade chipset. When booting off of
CD-ROM, anaconda starts, detects the correct video chipset and fails detecting
the display (as expected -- it's a laptop) so falls back to generic.
After that, the screen goes black while starting X and the console is completely
locked. VCs cannot be switched.
Now I'm going to try forcing a text install
Same results with lowres. Anaconda starts, box locks starting X
same results with nofb, and when forcing 1024x768x8bit
FWIW, after a text-mode upgrade completed, XFree86 4.2 worked with the video
card, so it's not a matter of the Trident simply being unsupported by RH.
What are the PCI ids for the video card?
pci bus 0x0001 cardnum 0x00 function 0x00: vendor 0x1023 device 0x8420

This is still broken in beta2, though it looks slightly different (progress? ;-).
linux switches to graphical mode, turns the screen mottled white (like when you
overdrive an LCD), and is hung.
This happens regardless of which options I use to boot
Forgot to change the version....

Still broken in beta3....
Do you have an X configuration that works on this card, and if so please tell me
the X server driver and attach the X config file?
With 3.3.6 on older RH releases, it used the XFree86_SVGA driver. I don't still
have an XF86Config file around from that.
In the beta cycles, 4.2.0 has been working just fine with it (first version of
XFree86 4 to do so; 4.1 was supposed to support it, but I never could get RH 7.2
to drive it using anything except 3.3.6).
XF86Config-4 will be attached.

working XF86 4.2 config file -- automatically generated during install
I noticed the working config is using 1152x864 - is this the resolution of the LCD?
Actually, the config file lists 1152x864, but it's running at 1024x768.
Bizarre, but what anaconda put on the disk worked so I've not monkeyed with it....
With 3.3.6 on RH <= 7.2, I ran this machine at 1024x768 as well.
I just changed the config to 1024x768 -- thanks for pointing that out.
Attached will be the log from it working with 4.2.0 on beta3, running at
1024x768, in case the video mode info from that will be useful.

log from working XFree86 4.2 startup
Still true with beta4. Text install works, graphic locks the screen, X works
I have not been able to locate this hardware unfortunately.
Closed, since #64397 became the same as this, with a potential solution
