| BluesKaj | Hi all | 13:59 |
|---|---|---|
| * arraybolt3 boots up the latest daily to see what happens | 16:35 | |
| arraybolt3 | hmm, still booting into an autologin KDE session | 16:35 |
| arraybolt3 | and the casper version is fully up-to-date | 16:36 |
| arraybolt3 | alright, so that's wrong | 16:36 |
| arraybolt3 | the installer prompt session is there though... | 16:37 |
| arraybolt3 | gah, I see what I did wrong | 16:44 |
| arraybolt3 | slipped past vorlon too so I don't feel quite so bad :P | 16:45 |
| arraybolt3 | ok, I have hit very strange behavior with the new kubuntu-installer-prompt. | 22:52 |
| arraybolt3 | In a VM, it works fine. | 22:52 |
| arraybolt3 | On physical hardware (HP Pavilion dv7) it instantly segfaults. | 22:52 |
| arraybolt3 | Files are identical, ISO download is good, flash drive is good according to both balenaEtcher's verification and casper-md5check. | 22:53 |
| * tsimonq2 hands arraybolt3 a valgrind, a GDB, and a large hammer | 22:53 | |
| arraybolt3 | ...wha?! | 22:53 |
| arraybolt3 | tsimonq2: thanks :P | 22:53 |
| tsimonq2 | arraybolt3: Warning, it will break your brain for like four hours the first goaround. :P | 22:53 |
| arraybolt3 | meh, I've used both those tools before, no big deal. | 22:53 |
| arraybolt3 | valgrind is slow though | 22:53 |
| tsimonq2 | To be fair, it does a *lot*. ;) | 22:54 |
| arraybolt3 | alright, hitting it with gdb and debuginfod | 22:54 |
| tsimonq2 | <3 | 22:55 |
| arraybolt3 | this is the first time in my life I've had software I wrote have a hardware-triggered failure. | 22:55 |
| arraybolt3 | which probably means I've been lucky up until now :P | 22:55 |
| tsimonq2 | bah my gut tells me it's related to NM | 22:55 |
| tsimonq2 | or perhaps the multi screen logic | 22:56 |
| arraybolt3 | oh that could be true | 22:56 |
| arraybolt3 | either that or my ancient NVIDIA card throwing a tantrum, but more likely that. | 22:56 |
| tsimonq2 | old NVIDIA cards are prone to tantrums, I wouldn't rule that out so quickly ;P | 22:57 |
| tsimonq2 | (I no longer have that opinion about new NVIDIA cards after talking to Mike btw) | 22:57 |
| arraybolt3 | yeah this machine is old enough there aren't proprietary drivers for the card anymore. | 22:58 |
| arraybolt3 | It's Nouveau or bust (or patch the NVIDIA drivers which is questionably legal and definitely risky) | 22:58 |
| tsimonq2 | niceeeeeeee | 23:04 |
| arraybolt3 | ooof, yeah I definitely shouldn't rule out the NVIDIA card, I have ample evidence that this machine is... on its last leg. | 23:08 |
| arraybolt3 | (opened System Monitor and the graphics are berzerk) | 23:09 |
| arraybolt3 | (looks like possible VRAM failure) | 23:09 |
| arraybolt3 | and now a total system freeze. Nice. | 23:09 |
| arraybolt3 | I don't see any obvious memory management errors looking at the code, so I'm going to hope it's a graphics driver issue. | 23:17 |
| arraybolt3 | Switching to an Intel-based machine now. | 23:17 |
| arraybolt3 | *an Intel-based machine with crummy Broadcom WiFi | 23:57 |
