[Bug 2059847] Re: Input lag or freezes on Nvidia desktops with X11
Upstream Gnome 46 made a lot of changes recently to improve performance and input lag in Gnome-Terminal. Those changes are separate from this bug. I don't know whether those changes were backported to Ubuntu 22.04, which ships Gnome 42. That's a question for Daniel or someone else at Canonical. See https://bxt.rs/blog/just-how-much-faster-are-the-gnome-46-terminals/ and note that the graphs are only talking about lag in the neighborhood of 40-50ms, which is probably just barely perceptible. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2059847 Title: Input lag or freezes on Nvidia desktops with X11 To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2059847/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 2059847] Re: Input lag or freezes on Nvidia desktops with X11
Hi Daniel, No, not multi-GPU. It's an AMD system with no integrated graphics and only one Nvidia card. One monitor plugged in, one TV plugged in to that card via HDMI. But the TV is usually turned off, and disabled in Settings | Displays. Running Xorg, not Wayland. This doesn't look like bug 1876632; it's not suspend- or VT-switch- related. Maybe I shouldn't have called it "corruption"; what I'm seeing looks like gnome-terminal just... deciding not to render something that it should; characters don't echo. No wild colors or randomized textures or anything like that. Seems like either a problem within gnome- terminal, or GPU command buffers just getting dropped on the floor. Awfully similar to this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2059847 Title: Input lag or freezes on Nvidia desktops with X11 To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2059847/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2059847] Re: Input lag or freezes on Nvidia desktops with X11
threadbareobserve, the nvidia driver can be downgraded to 535 without too much work. I'd make sure all the related packages are removed before installing 535. Might help the developers to know what version of Ubuntu you're running. I'm running a 22.04 desktop with a 4070 card, and the PPA does *not* fix the problem for me. It removes the lag, but that means the corrupted screen just happens faster. This is a bit intermittent and hard to pin down, but I've particularly noticed this after attempting to paste text into Gnome-Terminal; only the first few pasted characters might be echoed, then it gets into a state where keyboard input is processed but not all of it is echoed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2059847 Title: Input lag or freezes on Nvidia desktops with X11 To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/2059847/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1879401] Re: [XPS 13 7390 2-in-1, Intel Icelake HDMI, Digital Out, HDMI] sound rarely works
I don't know if it's relevant; it may very well not be, because after this kernel message (described below) things sometimes succeed, or sometimes fail. But I noticed that there's a new feature in drm-tip (but not in mainline 5.8), for HDMI silent stream audio. I turned it on. It seems to work well, but only if power_save=0 is also specified. So I'm booting with two additional options on the kernel commandline: snd_hda_intel.power_save=0 snd_hda_codec_hdmi.enable_silent_stream=Y When configured like this, it seems like 100% of the time there is this message when booting with HDMI already plugged in: snd_hda_codec_hdmi hdaudioC0D2: Monitor plugged-in, Failed to power up codec ret=[-13] I'm attaching the full dmesg from a run with debug turned on. This particular run seemed to fail to output audio at first, then it eventually succeeded after changing the output source in sound settings a few times. So I'll attach two files from the same bootup of this machine, if you do a "diff" between them you will see that "success" simply picks up where "failed" left off.

@kaihengfeng, Sure. I'm attaching the "dmesg -H" output from a run that worked. My odds of success lately have been a bit better than "rarely works", but I still often need a few retries to get it working. A "retry" could mean unplugging and re-plugging the hub or HDMI cable, or simply suspending and resuming the laptop. HDMI port detection has been flaky on most kernels I've tried. This means that sometimes I will get neither video nor audio, and will have to retry. Other times, I will get video but no audio. What happened *this* time was that I had to retry twice to get video, but the first successful attempt which had video, also had audio. ** Attachment added: "working-dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879401/+attachment/5385431/+files/working-dmesg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879401 Title: [XPS 13 7390 2-in-1, Intel Icelake HDMI, Digital Out, HDMI] sound rarely works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879401/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I did some more testing today: * linux-image-5.4.0-31-generic --> not any better * linux-image-5.4.0-32-generic --> not any better * linux-image-5.6.0-1010-oem after removing kernel command line pcie_aspm.policy=powersupersave --> not any better * linux-image-5.4.0-32-generic after removing kernel command line pcie_aspm.policy=powersupersave --> seems better so far, but of course this is something of an intermittent problem, so time will tell. However, there is still a very reproducible similar problem, in that any time I switch to surround sound mode and back to stereo that breaks it permanently. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879401 Title: [XPS 13 7390 2-in-1, Intel Icelake HDMI, Digital Out, HDMI] sound rarely works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879401/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

apport information ** Tags added: apport-collected ** Description changed: I have an Ice Lake laptop (Dell 7390 2-in-one) which I am connecting to a TV over HDMI via a Novoo USB-C multiport adapter. This is not a Thunderbolt device, it is just USB-C. It seemed like things used to work fine before I upgraded this system from Ubuntu 19.10 to 20.04, although I couldn't say for certain at this point. But I'm having a ton of difficulty getting audio output over HDMI. Getting it to work requires a lot of retries to reinitialize the device (either by suspending/resuming the laptop, or plugging/unplugging the HDMI cable and/or the multiport adapter). It does work sometimes, but my success rate is very low at this point. Even when it does work, it's brittle: any change to the output port (to speaker and back to HDMI, or from stereo to surround and back) will often break the audio. This fact seems to suggest that the problem doesn't have anything to do with the low-level initialization of the HDMI port; I'd be looking at some mid-layer code. To be clear, there doesn't seem to be any particular symptom, or anything of interest in the logs, other than an absence of sound output.

We have some servers with TLSv1.0 disabled now, and I've tested your Precise JDK7 package against those--this works, the old package does not connect and the new package connects. I will follow up with a JDK6 test. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1482924 Title: Regressions due to USN-2696-1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/1482924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Another small test program. When run on the openjdk-6 PPA test package,
it only sends a TLSv1.0 ClientHello. Compare what happens when you
change the USE_DEFAULT constant to 'true':

[Bug 1482924] Re: Regressions due to USN-2696-1
I should clarify that my tests results for 6b36-1.13.8-0ubuntu1 are based on a modified java.security file which removed SSLv3 from the jdk.tls.disabledAlgorithms property. That may be the reason why they show SSLv3 as a default-enabled algorithm. Also, I was finally able to test your Wily package (I had to install an image in VirtualBox.) Unlike the openjdk-6 package from the PPA, it works as expected in the sense that TLSv1.2 is on by default: nbryant@wily:~$ java -version java version "1.7.0_79" OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-1ubuntu1~ppa3) OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode) nbryant@wily:~$ java TLSVersions java.vendor java.versionproto enabledProtocols Oracle Corporation 1.7.0_79TLSv1.2 SSLv3,TLSv1,TLSv1.1,TLSv1.2 Oracle Corporation 1.7.0_79TLSv1.1 SSLv3,TLSv1,TLSv1.1 Oracle Corporation 1.7.0_79TLSv1 SSLv3,TLSv1 Oracle Corporation 1.7.0_79TLS SSLv3,TLSv1,TLSv1.1,TLSv1.2 Oracle Corporation 1.7.0_79SSL SSLv3,TLSv1,TLSv1.1,TLSv1.2 This is a little weird though, SSLv3 is on, even though I have this in java.security: jdk.tls.disabledAlgorithms=SSLv3, DH keySize < 768 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1482924 Title: Regressions due to USN-2696-1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/1482924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1482924] Re: Regressions due to USN-2696-1
See this issue to drop RC4 support in the Chromium project: https://code.google.com/p/chromium/issues/detail?id=375342 Lots of good discussion but especially comment #44, #49, and perhaps the real key takeaway is comment #53: -- quote -- #53 t...@ritter.vg On the topic of PCI and CVSS scores, I talked with a QSA. Because of the 4.3 scores and general badness, PCI 3.1 was released recently and marks TLS 1.0 and below as unacceptable. Anyone wanting to use it must document a Risk Mitigation and Migration Plan. Which people do by saying "We have clients who haven't upgraded." But in newly deployed infrastructure the PCI Council is actually saying that they can't deploy TLS 1.0 or below at all, and to strand any older clients. I don't imagine this significantly affects opinions on UI treatment (including keeping the EV badging), but wanted to add some context I learned today. See also: https://www.pcisecuritystandards.org/documents/Migrating_from_SSL_Early_TLS_Information_Supplement_v1.pdf -- end quote-- Thus, if openjdk-6 and -7 continue to send a TLSv1.0 ClientHello by default, they soon risk losing connectivity to significant portions of the secure WWW. As a PCI compliant shop, this is already an issue here and we have some upcoming deadlines to make some changes. At the moment, I have seen 3 specific examples of broken connectivity: (1) web service gateway for an airline reservation system which refuses to negotiate CBC unless protocol level is TLSv1.1 or newer. This site is behind a source-IP based packet filter so I can't have anyone else test against it. (2) The public-facing internet-booking website for an airline (VA), which refuses to negotiate CBC at all, even on TLSv1.2, and does not support AEAD ciphers. The only option for this one is RC4 (3) The SOAP service endpoint for a payment service provider; this one is a lot like (2) - only RC4. This is also behind a source IP filter Tiago, under the circumstances, what kind of test code would you like to see? It is not possible to write a pure-Java test client and server which mimics the behavior of example (1), because an SSLServerSocket only enables/disables cipher suites globally across all protocol levels. I'm not sure what can responsibly be done about examples like (2) and (3), but it seems probably that sites like example (1) will become more common. ** Bug watch added: code.google.com/p/chromium/issues #375342 http://code.google.com/p/chromium/issues/detail?id=375342 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1482924 Title: Regressions due to USN-2696-1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/1482924/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed:
Due to [CBCATT], some server administrators (including the webservices
gateway for a major airline reservations provider) choose to disable CBC
ciphersuites unless the protocol level is TLSv1.1 or later; [TLS1.1]
introduced an explicit CBC IV to guard against such attacks. (See
[TLS1.1] section 1.1) On such servers, disabling all CBC ciphersuites
may leave only RC4 as a trusted cipher.
JDK7 introduced support for TLSv1.2, but chose not to enable it by
default, due to a policy of not changing such defaults in minor
revisions. JDK8 enables TLSv1.2 by default.
- On Ubuntu, due to USN-2696-1, starting with the openjdk-7-jre-
- 7u79-2.5.6-0ubuntu1.12.04.1 package, RC4 is disabled by default but the
- protocol default remains TLSv1.0.
+ On Ubuntu, due to USN-2696-1, starting with the

but the protocol default remains TLSv1.0. This can leave no remaining trusted
ciphers, and
+ negotiation can fail.
Workaround: on OpenJDK7, it is possible to either use
SSLContext.getInstance("TLSv1.2") or re-enable RC4 via
SSLSocket.setEnabledCipherSuites(), but neither workaround is viable if
one doesn't have access to 3rd-party source code.
