consoles (ttyX) all dark after resume (from hibernate)

[kamome]

After a hibernate and resume this system (dapper flight5 on a via mII12000) now seems to works fine, X, networ... - only the tyyX stay dark. I can still use them, though, and get some greenish spots, every once in a while, instead of normal output.

Seemingly identical effects present without hibernation (only after starting X) at bug 40297. Cause may be different, will not mark either as a duplicate at this time.

There are numerous reports on seemingly identical issues, all related to the framebuffer VTs / consoles not working when X is run. This occurs with varying hardware (and varying kernel versions), so the issue may be wider than previously suspected, and possibly related to something that these occurrences have in common.

However, even as these reports have much in common, I am hesitant to mark any as duplicates, since the hardware varies (e.g. four different graphics cards), and because the cause may or may not be the same.

As I summarised these reports, I find it beneficial to attach the summary to each report. Apologies to recipients of Ubuntu Bugs & Ubuntu X SWAT for having to receive multiple copies of the same.

A brief summary follows:

Four reports, with the common behaviour that the framebuffer consoles stop working _as soon as X starts_:
- Bug 21416 - reported by felix.rommel. Acer Aspire 1350 with a Via KN400 Unichrome graphics card.
- Bug 29407 - unsure if original report is related or caused by a different issue, but all comments are related. Comments by Ignacio Lago Fontán, Compaq Evo N600c, ATI Radeon Mobility M6 LY; also by Thilo Six.
- Bug 40297 - reported by kko. Matrox G450 graphics card.
- Bug 42974 - reported by Richard Laager. HP dv800 with a GeForce Go 7400 graphics card.

A fifth report, with identical behaviour (fb stops working with X running), but only after hibernate + resume):
- Bug 36904 - reported by kamome with "dapper flight5 on a via mII12000".

A further report that may or may not be related, but lacks details (i.e. does the fb not work at all, or only stop working after X has been started? what equipment?):
- Bug 42168 - reported by vertiger.

Hi kamome.

Thanks for the summary :) Does this problem persist when using the latest Edgy beta? Thanks in advance.

We are closing this bug report as it lacks the information, described in the previous comments, we need to investigate the problem further. However, please reopen it if you can give us the missing information and feel free to submit bug reports in the future.

I have the same problem under Hardy (I think I also had it under gutsy, just kind of ignored it.) Now that I'm hibernating a lot it's really annoying.

So a direct summary:
Hibernate machine
Virtual Terminals Ctrl-alt-F* are either blank, or show a few random splotches of green and blue. My primary desktop is unaffected, everything seems fine.

Here's lspci -v:
00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller])
 Subsystem: Gateway 2000 Unknown device 4043
 Flags: bus master, fast devsel, latency 0, IRQ 16
 Memory at f0000000 (32-bit, prefetchable) [size=128M]
 Memory at ffa80000 (32-bit, non-prefetchable) [size=512K]
 I/O ports at ec00 [size=8]
 Capabilities: [d0] Power Management version 1

However, I don't see any information requested in previous comments. If you could clarify what else is needed, that would be great.

Sorry, the machine is an Emachine's T4010 : 2.8gHz Celeron, 512 mb ram, the branding is Intel Extreme Graphics2 3D on the integrated graphics.

[Luke Schlather (luke2760)]

Disabling grub splash screen solved it. I've been meaning to turn that off anyway. But if you need anything else to solve this let me know, I can turn it back on if you want to try to narrow down the cause.

[Brian Murray (brian-murray)]

Do you mean that you disabled usplash, which shows the Ubuntu logo and the "throbber" that indicates the system is booting?

[Luke Schlather (luke2760)]

Yeah, sorry. I removed the "quiet splash" (or quiet usplash, I should've saved my menu.lst) from the line beginning

 #defoptions=

So now instead of the throbbing progress bar, I have a list of things loading up.

The usplash package has been superseded by plymouth and has been removed from the Ubuntu archive. Closing all related bugs.
