Bug ID: 95059
Summary: DVI port failure with external TMDS transimitter for
T510/T5555/C90LE thin clients
Product: xorg
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Driver/openchrome
Assignee: openchrome-devel@lists.freedesktop.org
Reporter: huangra...@126.com
With my latest testing for DVI port with UMS 0.4.0 driver, here is the current
status for the result of my thin clients:
DVI-I DVI-D
HP T510(VX900) fail suc
HP T5555(VX900) fail suc
Wyse C90LE(VX855) fail X
Wyse V90LE(CN700) suc X
From the result we tested, it shows for DVI-D port for T510/T5555, the UMS
driver is working fine; By contrast, for T510/T5555 DVI-I port, the UMS driver
is failed to work. The possible reason is that DVI-I uses a external TMDS
transmitter Silicon Image Sil164 which current UMS driver does not support.
For V90LE and C90LE, the result is very interesting because they both uses
VT1632 as the external TMDS transmitter, but the result is totally different.
Thanks,
Frank
