Bundled libgbm incompatible with NVIDIA 590 driver

[leolannenmaki]

I upgraded my bazzite-nvidia-open system and got the new driver (xorg-x11-nvidia 3:580.95.05-1.fc43 -> 3:590.44.01-1.fc43) which, I suspect, caused the appimage not to boot. It doesn't even show a window.

Potentially relevant log messages:

After some debugging I got it to run after I did this trying to force system gbm:

./ghostty --appimage-extract
cd squashfs-root
rm -rf shared/lib/libgbm* shared/lib/gbm/
./AppRun

Working logs differs a bit::

Hi, that kmsro: driver missing error was seen before here

Does alacritty run?

---

After some debugging I got it to run after I did this trying to force system gbm:
./ghostty --appimage-extract
cd squashfs-root
rm -rf shared/lib/libgbm* shared/lib/gbm/
./AppRun

Did this work?

You need to run ./AppDir/sharun -g as well so that sharun regenerates its cache file, otherwise it will be setting GBM_BACKENDS_PATH to the deleted gbm directory.

edit: nvm you said it ran after doing that.

Also test doing the ./AppDir/sharun -g because it maybe a bug related to gbm that gets fixed by not using it.

Do you have the issue with the nightly releases? https://github.com/pkgforge-dev/ghostty-appimage/releases/tag/tip

Both work after rm -rf shared/lib/libgbm* shared/lib/gbm/ and both print out a MESA-LOADER error that ./AppDir/sharun -g makes go away.

[Samueru-sama]

What do you have /usr/lib/gbm or /usr/lib64/gbm?

I believe nvidia ships its own gbm backend iirc.

[leolannenmaki]

both actually.

@leolannenmaki now test this please:

extract the appimage again but do not delete anything, instead run this:

sed -i -e 's|GBM_BACKENDS_PATH|GBM_BACKENDS_XXXX|' ./AppDir/sharun ./AppDir/bin/ghostty

And run ./AppDir/AppRun, does it work?

[leolannenmaki]

Yes, it does run. No errors.

Edit. Tested this version only https://github.com/pkgforge-dev/ghostty-appimage/releases/tag/tip

[Samueru-sama]

@leolannenmaki cool, now test this instead as well (so I can fix this as quick as possible since it has to be reported to sharun):

• extract the appimage again and do this instead:

ln -s /usr/lib64/gbm/nvidia-drm_gbm.so ./AppDir/shared/lib/gbm

Does it work?

[leolannenmaki]

chmod +x Ghostty-1.3.0-main+3a89c8a-x86_64.AppImage
./Ghostty-1.3.0-main+3a89c8a-x86_64.AppImage --appimage-extract
ln -s /usr/lib64/gbm/nvidia-drm_gbm.so ./AppDir/shared/lib/gbm

Works, no errors.

[Samueru-sama]

pkgforge-dev/Anylinux-AppImages@753b3ba will fix it for now.

It is not a perfect solution, since the symlink will only work in rpm and archlinux based distributions, it will not work on debian based systems since those have the extra x86_64-linux-gnu dir in their path.

Now I will report this to sharun so that the nvidia prime logic it already has also applies to the gbm backends.

edit: Thanks a lot @leolannenmaki for the report and tests

[Samueru-sama]

Looks like GBM_BACKENDS_PATH can accept multiple paths.

@leolannenmaki can you check doing the sed -i -e 's|GBM_BACKENDS_PATH|GBM_BACKENDS_XXXX|' ./AppDir/sharun ./AppDir/bin/ghostty again and then set the variable manually to this:

export GBM_BACKENDS_PATH="./AppDir/shared/lib/gbm:/usr/lib64/gbm"

Does it work?

I'm sorry, but I can't until Wed. I'm traveling and not at my desktop until then.

./ghostty.appimage --appimage-extract
sed -i -e 's|GBM_BACKENDS_PATH|GBM_BACKENDS_XXXX|' ./AppDir/sharun ./AppDir/bin/ghostty
export GBM_BACKENDS_PATH="./AppDir/shared/lib/gbm:/usr/lib64/gbm"
./AppDir/bin/ghostty

this worked for me.

this worked for me.

Worked for me as well.
