Hi guys,
I am having an issue here of this driver. The problem I have is after a certain amount of time, my touchpad will definitely have a problem, that the mouse behaves as if I am holding the left button no matter what. This issue is definitely going to happen and it happens to all desktop manager I've tested, including gnome, kde, lxde. The way I temporarily fix the issue is by doing the following: $ sudo rmmod hid_multitouch $ sudo modprobe hid_multitouch this may fix the issue. when the certain amount of time is longer than a period, this won't work and will cause gnome to restart. so I bet it's a driver issue. Since it's definite and time related and could introduce trashes of other processes, it smells like a stack or buffer overflow. I am not sure which log file to provide to locate the issue. I don't have this problem in Wheezy so I guess it's neither a bug introduced in a newer version of synaptics, or Wheezy doesn't use this driver at all. It bothers me too much and I can't really use my touchpad. I hope this issue will be investigated. following is my finding in dmesg, doesn't seem to reveal anything useful: [239751.338142] ------------[ cut here ]------------ [239751.338155] WARNING: CPU: 1 PID: 10469 at /build/linux-xkTWug/linux-3.16.7-ckt11/drivers/gpu/drm/i915/intel_pm.c:5992 intel_display_power_put+0x127/0x150 [i915]() [239751.338156] Modules linked in: ccm pci_stub vboxpci(O) vboxnetadp(O) vboxnetflt(O) binfmt_misc cpufreq_conservative vboxdrv(O) cpufreq_userspace cpufreq_powersave cpufreq_stats deflate ctr twofish_generic twofish_avx_x86_64 twofish_x86_64_3way twofish_x86_64 twofish_common nfsd camellia_generic auth_rpcgss oid_registry camellia_aesni_avx2 nfs_acl camellia_aesni_avx_x86_64 nfs camellia_x86_64 lockd fscache serpent_avx2 serpent_avx_x86_64 sunrpc serpent_sse2_x86_64 xts serpent_generic blowfish_generic blowfish_x86_64 blowfish_common cast5_avx_x86_64 cast5_generic cast_common des_generic cbc cmac xcbc rmd160 sha512_ssse3 sha512_generic sha256_ssse3 sha256_generic hmac crypto_null af_key xfrm_algo snd_hda_codec_hdmi ath3k btusb bluetooth 6lowpan_iphc joydev uvcvideo videobuf2_vmalloc videobuf2_memops [239751.338199] videobuf2_core v4l2_common videodev media iTCO_wdt iTCO_vendor_support x86_pkg_temp_thermal snd_hda_codec_realtek intel_powerclamp intel_rapl snd_hda_codec_generic arc4 coretemp acer_wmi sparse_keymap kvm_intel kvm crc32_pclmul ghash_clmulni_intel ath9k aesni_intel ath9k_common aes_x86_64 ath9k_hw lrw gf128mul glue_helper ath ablk_helper cryptd mac80211 evdev pcspkr serio_raw rtsx_pci_ms cfg80211 snd_hda_intel rfkill snd_hda_controller snd_soc_rt5640 i915 memstick snd_soc_rl6231 snd_soc_core snd_hda_codec drm_kms_helper snd_hwdep snd_compress mei_me snd_pcm drm regmap_i2c snd_timer snd mei soundcore i2c_algo_bit lpc_ich shpchp i2c_i801 battery snd_soc_sst_acpi wmi ac i2c_designware_platform i2c_designware_core video button processor thermal_sys loop fuse parport_pc ppdev lp parport autofs4 [239751.338246] ext4 crc16 mbcache jbd2 dm_mod sg sd_mod crc_t10dif crct10dif_generic rtsx_pci_sdmmc ehci_pci ehci_hcd xhci_hcd ahci crct10dif_pclmul crct10dif_common libahci r8169 crc32c_intel mii libata rtsx_pci mfd_core scsi_mod usbcore usb_common i2c_hid hid sdhci_acpi sdhci i2c_core mmc_core [last unloaded: hid_multitouch] [239751.338270] CPU: 1 PID: 10469 Comm: Xorg Tainted: G W O 3.16.0-4-amd64 #1 Debian 3.16.7-ckt11-1+deb8u5 [239751.338272] Hardware name: Acer Aspire E5-571/EA50_HB , BIOS V1.08 06/20/2014 [239751.338274] 0000000000000009 ffffffff8150b4c5 0000000000000000 ffffffff81067767 [239751.338278] ffff88003691002c ffff880252d81800 ffff880036910000 000000000000000b [239751.338281] ffff880036918520 ffffffffa044e067 ffff880252d81800 ffff880252d81800 [239751.338285] Call Trace: [239751.338289] [<ffffffff8150b4c5>] ? dump_stack+0x41/0x51 [239751.338294] [<ffffffff81067767>] ? warn_slowpath_common+0x77/0x90 [239751.338308] [<ffffffffa044e067>] ? intel_display_power_put+0x127/0x150 [i915] [239751.338325] [<ffffffffa04ac77c>] ? intel_dp_get_modes+0x6c/0x100 [i915] [239751.338336] [<ffffffffa03ac966>] ? drm_helper_probe_single_connector_modes_merge_bits+0x286/0x370 [drm_kms_helper] [239751.338348] [<ffffffffa0367ccd>] ? drm_mode_getconnector+0x3dd/0x450 [drm] [239751.338353] [<ffffffff811bb0f0>] ? poll_select_copy_remaining+0x140/0x140 [239751.338364] [<ffffffffa03598b7>] ? drm_ioctl+0x1c7/0x5b0 [drm] [239751.338370] [<ffffffff811ba4ef>] ? do_vfs_ioctl+0x2cf/0x4b0 [239751.338374] [<ffffffff811ba751>] ?
